Not logged in. Hi, We've been running Dokuwiki internally for a few months now, and have been using LDAP authentication with our active directory. However, we would now like to publish the WIKI out on the interent for our external clients. Is there anyway to automatically pass the credentials entered in the IE pop up through to the WIKI authentication method, so users only have to enter their details once?
I wonder if this would solve a problem I've been researching? The wiki I'm setting up is completlely private, so when someone browses to it, they get the error page indicating they have no rights and may need to log in. I've been trying to figure out how to fix this for the last couple of hours.
I'd rather them be greeted by the login page if they are not logged in and the main page if they are logged in when they go to the URL representing our wiki. In reply to post 1. Read this if you don't get any useful answers.

If not, could you recommend an authmodule that would work? LDAP user search: Operations error [ldap. Thanks Ben. You should use the LDAP backend. Before doing the changes suggested make sure the LDAP backend works with separate login. If I then click on the login page, I see that the username field is pre-filled for me with domain.
This is the same if I enter the login in username domain. So I'm thinking that it is kind of working, but the basic http auth is trying to pass the domain. Do you know how I might get the logon to drop the domain prefix? I set debug to 0, but it didn't fix it. OK, just got it nearly working! I can live with this, as long as I remind my users they have to enter their usernames in this format, but it would be nice if they cold drop the domain.
Server Fault is a question and answer site for system and network administrators. It only takes a minute to sign up. The client is CentOS. You may wish to turn off SASL and use simple authentication with the "-x" option. For example, a search to find a particular user.

The actual search, in this example for a user record, is given in the filter as the last argument.
Bind as the application user. Search for the DN distinguished name of the user to be authenticated. Bind as user to be authenticated using DN from step 3.You can configure which authentication method to use. You can configure different authentication methods for incoming Web requests and for outgoing Web requests. The following authentication schemes are supplied with Forefront TMG:.
Forefront TMG also supports third-party authentication schemes that are registered with Web filters. For more information about third-party authentication schemes, see the reference page for the FPCAuthenticationScheme object. Other Web browsers may support only Basic authentication. Be sure that the client Web browsers can use at least one of the authentication methods that you specify in the incoming Web request properties and outgoing Web request properties.
Otherwise, the client will not be able to access the requested object. A Web listener can be configured to use any of the built-in Windows authentication methods supported by Forefront TMG or any combination of these methods to authenticate Web requests.
Alternatively, a Web listener for incoming Web requests can be configured to use an authentication scheme defined by an FPCAuthenticationScheme object for authentication. However, the Web listener for outgoing Web requests sent from a network can be configured to use only the built-in Windows authentication methods or the RADIUS authentication scheme.

Of course, restrictions made in the database and user columns still apply. This method should only be used when there is adequate operating-system-level protection on connections to the server. It is usually not appropriate by itself on a multiuser machine. However, you might be able to use trust even on a multiuser machine, if you restrict access to the server's Unix-domain socket file using file-system permissions.
Setting file-system permissions only helps for Unix-socket connections. Therefore, if you want to use file-system permissions for local security, remove the host The password-based authentication methods are md5 and password.
These methods operate similarly except for the way that the password is sent across the connection, namely MD5-hashed and clear-text respectively. If you are at all concerned about password "sniffing" attacks then md5 is preferred. Plain password should always be avoided if possible. If the connection is protected by SSL encryption then password can be used safely though SSL certificate authentication might be a better choice if one is depending on using SSL.
PostgreSQL database passwords are separate from operating system user passwords. If no password has been set up for a user, the stored password is null and password authentication will always fail for that user. The authentication itself is secure, but the data sent over the database connection will be sent unencrypted unless SSL is used.
For information about the parts of the principal, and how to set up the required keys, see Section If set to 1, the realm name from the authenticated user principal is included in the system user name that's passed through user name mapping Section This is the recommended configuration as, otherwise, it is impossible to differentiate users with the same username who are from different realms. The default for this parameter is 0 meaning to not include the realm in the system user name but may change to 1 in a future version of PostgreSQL.
Users can set it explicitly to avoid any issues when upgrading. Allows for mapping between system and database user names. See Section When you assign the proxy or proxy-anonymous credential level to a client, you also need to select a method by which the proxy authenticates to the directory server.
By default, the authentication method is nonewhich implies anonymous access. The authentication method may also have a transport security option associated with it. The authentication method, like the credential level, may be multivalued. For example, in the client profile you could specify that the client first tries to bind using the simple method secured by TLS.
These mechanisms allow for a secure password exchange without requiring TLS. However, these mechanisms do not provide data integrity or privacy. The client does not authenticate to the directory. This is equivalent to the anonymous credential level. If the client system uses the simple authentication method, it binds to the server by sending the user's password in the clear.
The password is thus subject to snooping unless the session is protected by IPsec. The primary advantages of using the simple authentication method are that all directory servers support it and that it is easy to set up. The client's password is protected during authentication, but the session is not encrypted. The primary advantage of digest-MD5 is that the password does not go over the wire in the clear during authentication and therefore is more secure than the simple authentication method.
If you are using Sun Java System Directory Server, the password must be stored in the clear in the directory. This authentication method is used in conjunction with the self credential mode to enable per-user lookups.
Access can be controlled in the directory server on a per-user basis.
The client binds using the simple method and the session is encrypted. The password is protected. Be especially careful that the userPassword attribute has the proper ACIs if it is stored in the clear, so that it is not readable. The following table summarizes the various authentication methods and their respective characteristics.
The authentication method can be specified for a given service in the serviceAuthenticationMethod attribute.Authentication means verifying the identity of someone a user, device, or an entity who wants to access data, resources, or applications. Validating that identity establishes a trust relationship for further interactions. Authentication also enables accountability by making it possible to link access and actions to specific identities. After authentication, authorization processes can allow or limit the levels of access and action permitted to that entity as described in Chapter 5, "Authorization: Privileges, Roles, Profiles, and Resource Limitations".
Oracle allows a single database instance to use any or all methods. Oracle requires special authentication procedures for database administrators, because they perform special database operations. Oracle also encrypts passwords during transmission to ensure the security of network authentication.
To validate the identity of database users and prevent unauthorized use of a database user name, you can authenticate users by using any combination of the methods described in the following sections:. Chapter 10, "Administering Authentication"discusses how to configure and administer these authentication methods. Some operating systems permit Oracle to use information they maintain to authenticate users.
This has the following benefits:. Once authenticated by the operating system, users can connect to Oracle more conveniently, without specifying a user name or password.
With control over user authentication centralized in the operating system, Oracle need not store or manage user passwords, though it still maintains user names in the database.
Audit trails in the database and operating system can use the same user names.
When an operating system is used to authenticate database users, managing distributed database environments and database links requires special care.

Authentication over a network is handled by the SSL protocol or by third-party services as described in the following subsections:.
It can be used for user authentication to a database, and it is independent of global user management in Oracle Internet Directory. That is, users can use SSL to authenticate to the database even without a directory server in place. Authentication over a network makes use of third-party network authentication services. If network authentication services are available to you, then Oracle can accept authentication from the network service. If you use a network authentication service, then some special considerations arise for network roles and database links.

It presumes that the third party is secure, and provides single sign-on capabilities, centralized password storage, database link authentication, and enhanced PC security. It does this through a Kerberos authentication server, or through Cybersafe Active Trust, a commercial Kerberos-based authentication server.
Authentication systems based on PKI issue digital certificates to user clients, which use them to authenticate directly to servers in the enterprise without directly involving an authentication server. Oracle provides a PKI for using public keys and certificates, consisting of the following components:.
These are used to sign user-specified data using a private key and certificate. The verification of the signature on data is done by using a trusted certificate. These are used to identify third-party entities that are trusted as signers of user certificates when an identity is being validated. When the user certificate is being validated, the signer is checked by using trust points or a trusted certificate chain of certificate authorities stored in the validating system.
If there are several levels of trusted certificates in this chain, then a trusted certificate at a lower level is simply trusted without needing to have all its higher-level certificates reverified.Authentication verifies a user's identity. Everyone who needs to access Tableau Server—whether to manage the server, or to publish, browse, or administer content—must be represented as a user in the Tableau Server repository. In all cases, whether authentication takes place locally or is external, each user identity must be represented in the Tableau Server repository.
The repository manages authorization meta data for user identities. Looking for Tableau Server on Linux? See Authentication. Although all user identities are ultimately represented and stored in the Tableau Server repository, you must manage user accounts for Tableau Server in an identity store.
There are two, mutually exclusive, identity store options: LDAP and local. For more information see Identity Store. As shown in the following table, the type of identity store you implement, in part, will determine your authentication options.
Access and management permissions are implemented through site roles. Site roles define which users are administrators, and which users are content consumers and publishers on the server. For more information about administrators, site roles, groups, Guest User, and user-related administrative tasks, see Users and Site Roles for Users.
In other words, in the default configuration, Tableau Server does not act as a proxy to external data sources. Such access requires additional configuration of the data source on Tableau Server or authentication at the data source when the user connects from Tableau Desktop.
Some authentication methods can be used together. The following table shows authentication methods that can be combined. Cells marked with an "X" indicate a compatible authentication set. Blank cells indicate incompatible authentication sets. If the server is configured to use local authentication, then Tableau Server authenticates users.
When users sign-in and enter their credentials, either through Tableau Desktop, tabcmd, API, or web client, Tableau Server verifies the credentials. To enable this scenario, you must first create an identity for each user. To create an identity, you specify a username and a password.
To access or interact with content on the server, users must also be assigned a site role. You can also create groups in Tableau Server to help manage and assign roles to large sets of related user groups e. When you configure Tableau Server for local authentication, you can set password policies and account lockout on failed password attempts. See Local Authentication.
