More or less every UDM function has a wrapper,  wrapper_func(), which initializes an LDAP connection (univention.admin.access). There are several reasons why this connection cannot be established, a common one (if feedback traceback can be trusted):

  LDAP_ConnectionError: Opening LDAP connection failed: {'desc': "Can't contact LDAP server"}

This causes an ugly UMC Traceback and does not help. Neither does it help the user (What? Error? UCS is broken?!) not does it help us when sending the feedback.

I would suggest presenting a real error dialogue like this:

"The connection to LDAP failed. These steps may help you:"

if dc_master:
  "Restart sldapd"
else:
  "Is the DC Master %s reachable (IP: %s)? If so, restart slapd there!"

"If this error persists and you have a support contract ..."

... and so on
