[Samba] Help with error msg OSX: pdb_ods.c:odssam_getsampwrid(1903)

[klubarpop]

I'd be appreciative if someone could give me some more details on the
following error message:

[2005/04/12 08:56:24, 1] pdb_ods.c:odssam_getsampwrid(1903)
  odssam_getsampwrid: rid<501> rid str<501>
[2005/04/12 08:56:24, 1] pdb_ods.c:odssam_getsampwrid(1903)
  odssam_getsampwrid: rid<501> rid str<501> 

This message occurs 5 to 10 times per day per PC user.  We're running SAMBA
3.0.5 on Macintosh OS X (not server).

I've goggled searched and didn't find anything and looked at the code which
didn't help me much.

Many thanks....
