I'm using one of the last CVS before (about one weeks before)the
official release of beta1.

In my LDAP directory I've configured a sambaUnixIdPool objectClass. At
the beginning the uidNumber was 3000(I've decided to set up it to this
value), but now in 3 weeks the value of this entry is 13699. Strange !
And I don't think that idmap.tdb has been delete to be regenerated ! The
only things we do : it's a net rpc vampire to resynchronized the SAM
with ou NT4 PDC !

Thank you,
