Summary:                    [patch] LDAP error while unregister UA
Description: 
Hi, 

While unregistering peer the following message appers:
================
*CLI> [Aug 31 23:25:20] ERROR[13092]: res_config_ldap.c:1331 update_ldap:
Couldn't modify dn:cn=????? ????????,ou=???? ??????,ou=??????????????
??????????,l=??????,o=??????-??????,c=UA,c=Global because No such attribute
   -- Unregistered SIP 'vtutov'
================

It's trying to LDAP_MOD_DELETE some atributes regardless of their
existance, and when are absent throws "No such attribute"

Please take in consideration that modifications are applied to set of
entries from ldap_search in turn, so there is no way to detect presence of
attributes before etry is actually processed.

Suggestion: need to check existance of attributes and delete only actual
ones. 

Corresponding patch supplied.

Ok, now it's clear. OpenLDAP 2.3.43 seems to be not completely standard
compatible. RFC notes (http://www.ietf.org/rfc/rfc2251.txt, p.32)

  replace: replace all existing values of the given attribute
             with the new values listed, creating the attribute if it
             did not already exist.  A replace with no value will delete
             the entire attribute if it exists, and is ignored if the
             attribute does not exist.

This issue might be closed without resolution.

Sorry for fakereport.
