[Samba] Samba 4 RPC hangs after a while

[Holger Martiker]

I additional find out that there is a Problem with uid "3000000".

Following requests work fine:

root at srv02:/usr/local/samba/bin# ./wbinfo --uid-to-sid=3000001
S-1-5-32-545
root at srv02:/usr/local/samba/bin# ./wbinfo --uid-to-sid=3000002
S-1-5-21-3477057243-790338134-802528447-501
root at srv02:/usr/local/samba/bin# ./wbinfo --uid-to-sid=3000003
S-1-5-21-3477057243-790338134-802528447-514

But when I request wbinfo for User 300000 Samba RPC stops working. (Without any Log Message and no process dies)

root at srv02:/usr/local/samba/bin# ./wbinfo --uid-to-sid=3000000 failed to call wbcUidToSid: WBC_ERR_WINBIND_NOT_AVAILABLE Could not convert uid 3000000 to sid

Is there a user missing?
The most files in sysvol have UserID 300000 so I think it’s a Problem in this direction.
Can I add a user with this UID?

Best regards,
Holger
