LDAP: member and group not very well working

Hi,

openfire version is 4.1.3.

openfire is backed by a directory (ApacheDS).

When configuring OpenFire, at the time of group validation, I can see that the counts in each group are correct: first group has 32 members for example.

But, when Openfire is running, then is no more anybody in each group. Why?

Thanks,
