When using LDAP authentication, users are authenticated against LDAP using the distinguished names (DN) that are stored in the Domain Authentication property in the Quality Center database. When the user
attempts to log in, and the DN information in Quality Center is invalid, the user is unable to log in to Quality Center.You can enhance the search so that when the DN information is invalid, Quality Center will also search on the LDAP server, using the LDAP import settings defined in Site Administration. If the user is found, the DN is updated in Quality Center, and an automatic login attempt is performed. To set this extended search, define a comma-separated list for the LDAP_SEARCH_USER_CRITERIA Site Configuration parameter. The possible values are username, email, fullname, phone, description. The order of the properties defines their priority if multiple results are found. For example, if the parameter is set to username and email, and two users are
found with the same user name on the LDAP server, their e-mail addresses are checked. If more than one user is found answering the set properties, an error message is returned. If the search for the user succeeds, the user is logged in to Quality Center.
