[Pki-devel] [PATCH] 519 Fixed problems in group operations.

Previously modifying the description of an empty group failed because the server tried to delete a uniqueMember attribute that did not exist because the group was already empty. The servlets and group subsystem has been fixed to retrieve the existing group data first, perform the changes on it, then save it back to the database. Also adding a new group will no longer require a description because it's not required by the LDAP object class. Ticket #818 -- Endi S. Dewata
