[Samba] Samba loose the user forward as member Server

Hi,
i am at the end of my knowledge.
Our PDC works fine all user can access the Samba Shares, Windows Logins 
are Working, all fine.

But our Member Server makes me ($=%§=(%(§=.

When i join the Domain all is fine and all Shares are working

net rpc join -S DOMAINSERVER -U Administrator
Using short domain name -- DOMAIN
Joined 'SERVER1' to domain 'DOMAIN'

net rpc testjoin -S DOMAINSERVER -U ADMINISTRATOR
Join to 'DOMAIN' is OK

but after some time, mostly over night the User forward to the PDC wont 
work anymore

the only thing what then works is to rejoin the domain
net rpc join -S DOMAINSERVER -U Administrator
after that all Shares work again, but that is not a solotuin to work with.

gives this and after around 1 min he stops

           ---------            -------
           DOMAIN               PDC

and all works fine


Does anyone of you have a idea what is wrong?
The last idea i have is to change from member Server to Standalone 
Server but this is only a workaround not a solution

[Samba] Samba loose the user forward as member Server

Hi,

Is your replication between you PDC and you member server working?

You can run "samba-tool drs showrepl". Which should help you determine
if the replication is functioning correctly.

Here is a related link to the Samba wiki that may help :-)

https://wiki.samba.org/index.php/Samba_AD_DC_Troubleshooting

Best Regards,

- Rylan
