Hi, I'm trying to add some users to ovirt using an AD. This is the configuration I used for a mediawiki site, which is working correctly: $wgAuth = new LdapAuthenticationPlugin(); $wgLDAPUseLocal = true; $wgLDAPDomainNames = array( "a_domain"); $wgLDAPServerNames = array( "a_domain"=>"site.example.com"); $wgLDAPEncryptionType = array( "a_domain"=>"clear"); $wgLDAPSearchStrings = array( "a_domain"=>"rom_domain\\USER-NAME"); $wgLDAPBaseDNs = array( "a_domain"=>"dc=company,dc=com"); Those are the commands I tried using: engine-manage-domains -action=add -domain=site.example.com-provider=ActiveDirectory -user= user.name -interactive engine-manage-domains -action=add -domain=a_domain -provider=ActiveDirectory -user=user.name@company.com -interactive engine-manage-domains -action=add -domain=a_domain -provider=ActiveDirectory -user=user.name@site.example.com -interactive And the output on all tries: Enter password: Error: Authentication Failed. Please verify the fully qualified domain name that is used for authentication is correct.. Problematic domain is: domain_used_in_command Failure while applying Kerberos configuration. Details: Authentication Failed. Please verify the fully qualified domain name that is used for authentication is correct. Can someone help me with the correct parameters? Best regards, Cristian Falcas
