[horde] Two different user storage in horde

[Manilal K M]

Hi all,
  I have a horde installation in which two backends(LDAP and MySQL)
are used. I have configured a composite driver and it works fine.
However when I list the users in the "Administration menu" only the
users from one backend is displayed. Is it possible to list the users
from both the backends at a time ? Please give me some guidance.

regards
Manilal
