Most applications first search the DN of a person by its uid (or email
adress or cn) so the DN
may vary.
Second I currently use the hierarchical approach because NSroles are
inherited along
the tree. So if the user help desk creates a user in the right tree leave,
they automatically
get the roles inherited they need for our applications. No manual
administration of static groups
needed. I wouldn''t even need NSroles, if all node names would be
translated
to Java/Applications-Roles
in the Java-World.

It would be really great if a moved person would belong to the same groups
and roles
afterwards. Today I correct it manually and have to write a tool that does
it automatically.

Every Java Application I know of. For a use rto login there is always this
sequence:
- anonymous bind to search the users DN from uid
- try to bind with DN and password
- if success get all group memberships of this user:
  o search all group entries where the DN is member
  o read attribute NSRoles
  o return the sum of both as java/application-roles

Tomcat returns the LDAP group membership as their ''cn'' and
the NSroles membership with their ''dn''. Only my LoginRealm is
able to
return both by their ''cn''.

Another wish: rename nodes which have leaves.
