I know, but I don't think it will possible here (this is an euphemism).
The UserFolder is a LDAPUserGroupsFolder, users data are stored in a
LDAP directory, with one branch for each CPS instance, and some user
data and schema varying from one branch to another. We don't have the
possibility to change this (it's part of a bigger system), and we don't
have the time to rewrite a custom LDAPUserFolder that could accomodate
this LDAP schema (this project was already very late when we took on it
and we have a *very* tight deadline - I hate this situation, but I have
to deal with it...). Any robust solution, as hackish as it may be, will
be just fine, as long as we deliver on time.
