samba - Aug 2007 - Winbind 3.0.25c: Problem joining 3.0.24 domain

I have a machine with a running samba 3.0.24 with winbind.
After an update to 3.0.25c I couldn't connect from win clients.
So I first tried to rejoin and got some errors about trust account problems - 
sorry didn't save them.
Then I deletet the account the tried a fresh join from the machine:

 net rpc join -Uaga -Waag -Serde
Password:
[2007/08/23 11:13:39, 
0] ./source/utils/net_rpc_join.c:net_rpc_join_newstyle(304)
  error setting trust account password: NT code 0x1c010002
Unable to join domain AAG.

When going back to 3.0.24 there is no problem with joining.

I found some similar posting when googling, but no solution.

Is it a known problem with 3.0.25 or could somebody point me to a solution?

Thanks
Angela
