Hello all!
  I have a question that is bugging me.  I am running a production RedHat
EL3 machine for about a year now with Samba version 3.0.9-1.3E.2
My personal user account stopped working two days ago.  I initially thought
my password expired, so I reset it in AD.
But I can log onto my win2k box without issue, but not into my linux file
server.  I checked to see if my machine had been cracked and no all is ok.

In summary:
   My active directory account was not deleted, moved, or edited at any
point around the time of this incident.
   Winbind no longer recognizes my linux UID to my SID.

Tests - assuming user is jdoe and AD Domain is AD_DOM:
   wbinfo -a jdoe%password completes with success.
   wbinfo -n jdoe completes with success and reports
"S-1-5-21-1708537768-776561741-1177238915-1127 User (1)"
   wbinfo -s S-1-5-21-1708537768-776561741-1177238915-1127 completes with
success and reports "AD_DOM+JDoe 1"
   wbinfo -S S-1-5-21-1708537768-776561741-1177238915-1127 fails and
reports "Could not convert sid
S-1-5-21-1708537768-776561741-1177238915-1127 to uid"
   wbinfo -u|grep jdoe reports nothing and confirms my suspicions.

So I have lost the database entry for my userid to sid.  I attempted to
recreate the user using wbinfo -c jdoe, but while the command line reported
"Generated user with RID 3000" I am still not able to be seen as a valid
account on the system.  I am assuming that I would need to reenter my uid
-> sid mapping into the database.  How can I go about this?  I know my old
uid was 1001.

So I am at a loss to my next steps.  Could you please advise.  Thank you
ever so much.
 Cheers, Peter.
