When I upgraded from samba 3.0.x to 3.4.x I ran into several issues.
First of all, I would look through the logs. (They did not attach to
your messgae.) I would also run "testparm -v" in case some default
settings have changed. NTLM should be enabled. If you require NTLMv2
that may cause problems (I couldn't get it to work.)
1st, with idmap and domain trusts: With 3.0.x the idmap entries
for trusted users were automatically created but they would expire in a
week and have to be manually purged. With 3.4.x the idmap cache issue
was fixed BUT the entries were no longer auto created. I had to
manually add idmap entries in ldap for users in the trusted domain (only
5 or 6 anyway.)
Do you use idmap for assigning user id's for users in primary domain? I
explicitly create user and group accounts. I would verify with
"pbedit -Lv username" and "pdbedit -Lv comptuername$" that
the samba
accounts haven't lost their unix id and that everything looks OK.
I also found with 3.4.x (vs 3.0.x) that the I needed to explicitly map
the guest user and group. This could affect the share permissions.
Generally I leave the share permissions unrestricted and rely on the
file system permissions for all the control.
Also make sure that the well known groups (e.g. Domain Users) look ok
with "net groupmap list" -
Multiple smbd processes is normal- should be one for each connection.
I also found it is better not to specify ports in the smb.conf.
Although samba does not use 445 for data, windows clients NOT using
wins may have problems connecting to to samba servers if 445 is not
running .
