As a followup, I have switched to the new server the problematic share
only, and it has been working no problem for the last two days.
I don't know what cured my issues: I upgraded samba from 3.0.10 to
3.0.11, changed kernel from 2.4.25-8mdk to 2.6.3-25mdk (now hp proliant
diagnostics are working even under 2.6, but I don't remember any hp
advisory telling that), upgraded to smbldap-tools 0.8.7 and re-imported
all users' credentials in ldap (though I doubt that these two steps had
anything to do with the solution of my problems).
I'm keeping my fingers crossed but it seems everything is working as
expected.
Bye
