LDAP User Import Application : NullPointerException returned by one group update makes the whole groups synchronization fail

[mouhb]

A NullPointerException is returned by the "Mapped groups daily updater" job when a mapped group is apparently empty (XWikiLDAPUtils#getGroupMembers(ldapGroupDN, context) returns null), see logs error.txt.

We have 2 issues here :

• Null returned value of method ldapUtils.getGroupMembers() is not correctly managed here
• If the update of one group fails (for some reason) it will make the whole synchronization update fail (the failure can be partial if the failed group is not the first one updated).

Version of LDAP User Import Application : 1.5.3.
