Hello
i think i now the problem
Zentyal 2.2 Docu
Slave status
The modules which have users like mail and filesharing can now be installed in the slaves and
they will use the users configured in the master Zentyal directory.
Some modules need extra actions to be executed when you add users,
for instance filesharing, which needs to create the user directories.
To do so, the master will notify the slaves about the new users and groups when
they are created , providing the opportunity for the slaves to perform the associated actions.
There can be some problems running these actions in some circumstances, for example if one of
the slaves is powered down. In this case, the master will remember that there are remaining
actions that must be performed and will periodically retry. The system administrator can also
check the slaves status on the menu Users and groups ‣ Slave status and then force the retry of
the actions manually at any time. From this section it is also possible to remove a slave.
There is an important limitation of the master/slave architecture. The master Zentyal server can not
have modules which depend of users and groups, for example filesharing and mail. If the
master has any of these modules installed, they must be un-installed before trying to register any
slave.
my master have only this modules installed
