While login to UVMS with a LDAP Account, we get the following error:

==========================================================
The server cannot be reached: LDAP Access denied

Check with unicheckldap:

This error messages shows clearly that the ldap server cannot be reached 


Description :Ldap authentication ceased to work. Login of LDAP user is no longer possible in UVC

 The problem is due to the fact that the name of the host running the ldap has changed and not been updated in the ldap.xml:
Parameter .... in ldap.xml is no longer valid and must be updated:vmsdmdc003uuuu.orsyptst.com

OS: Linux

The ldap.xml must be updated with the new hostname of the ldap server and uvms must be restarted.

The new settings must be checked with unicheckldap
