Thread:Extension talk:LDAP Authentication/$wgLDAPGroupDN vs wgLDAPRequiredGroups

I seem to get the $wgLDAPGroupDN function to work that is depricated, but not $wgLDAPREquireGroups with the same group ldap string. What is the differences between these two functions?

$wgLDAPRequiredGroups = array( "eLDAP"=>array( 'cn=COG-Approver,ou=Report View level,ou=Cognos,ou=apps,ou=Groups,o=MGMT' )	 );

$wgLDAPGroupDN = 'cn=COG-Approver,ou=Report View level,ou=Cognos,ou=apps,ou=Groups,o=MGMT';
