As a followup to this issue,

net ads join -U username at domain yields   ads_join_realm: Operations

  wbinfo -t yields   checking the trust secret via RPC calls failed
error code was NT_STATUS_ACCESS_DENIED (0xc0000022)
Could not check secret

net ads testjoin   [2008/01/23 11:08:13, 0]
  kerberos_kinit_password "machinename"@DOMAIN failed: Preauthentication
[2008/01/23 11:08:14, 0] libads/kerberos.c:ads_kinit_password(146)
  kerberos_kinit_password "machinename"@DOMAIN failed: Preauthentication
[2008/01/23 11:08:14, 0] utils/net_ads.c:ads_startup(191)
  ads_connect: Preauthentication failed
Join to domain is not valid

however kinit username at Domain works   wbinfo -u error looking up domain
users   wbinfo -g BUILTIN+system operators
BUILTIN+power users
BUILTIN+print operators
BUILTIN+account operators
BUILTIN+backup operators

none of which are from domain

We have another machine, that is identical to the failing machine in all
accounts except for it's machine name.  This other machine works well.
The only difference between the machines is that the working machine
joined the domain months ago when it was first set up and has worked
perfectly ever since.

In the meantime, the unix services where patched and we can now no
longer add any new linux machines to the domain, even when they have the
identical configuration.

Is this a known issue?  What can I try next?

best regards
