Im getting basically to "bugs" into my samba ... im using samba-3.0.2a (planning to upgrade soon, but atm i cant stop the service)
im using log level = 10


my basic problem is:


May 10 09:42:13 smb smbd[850]: [2004/05/10 09:42:13, 0] groupdb/mapping.c:init_group_mapping(139)

i have looked into mapping.c and found this:

  tdb = tdb_open_log(lock_path("group_mapping.tdb"), 0, TDB_DEFAULT, O_RDWR|O_CREAT, 0600);
         if (!tdb) {
          DEBUG(0,("Failed to open group mapping database\n"));
                 return False;
tdb = tdb_open_log(lock_path("group_mapping.tdb"), 0, TDB_DEFAULT, O_RDWR|O_CREAT, 0600);
         if (!tdb) {
                 DEBUG(0,("Failed to open group mapping database\n"));
                 return False;

as far as i can see its uses mode 0600 and i dont know why it starts bugging me, i have tried the following steps to see it could solve the problem, but it didnt.

smb:/usr/local/samba/var/locks# ls -l group_mapping.tdb
-rw-r--r--    1 root     staff        8192 May 10 05:47 group_mapping.tdb

everyone can read, and i still get those problems, as far as i can see thats the file.

smb:/usr/local/samba/var/locks# find / -name group_mapping.tdb -print
/usr/local/samba/var/locks/group_mapping.tdb


and because of this problem i think it aint executing the netlogon most of the times that happens (if i logon again with the user, the problem is solved) since i use my netlogon based on groups and many of my shares are based too, if samba cant map it, i will get troubles.

this samba server is already in production so i cant "play" with it unless i warn first. hope i can get this problem solved.

and this one which aint too bad:
for no reason i get sometimes those lines:
