This weird Winbind/Kerberos problem has been fixed again - hopefully for
I started to read the source code, followed the log messages at debug
level 10 and sniffed the network with tcpdump. Eventually, I figured
out that Kerberos is generating an inordinate amount of traffic, with
the result that the Windows server doesn't always get around to
answering the LDAP request and the user/group query then times out.
The solution is to reset the Windows Administrator password.
I remembered reading in the Samba howto guide that the Administrator
password reset also does something to Kerberos, so I tried it and it
worked. I haven't been able to break it again for the rest of the day.
