Yo dudes.... I have tried to implement both samba 2.2 and 3 i the company i working at, i had 30 workstations that used samba as a PDC.. i got three groups for the shares and i binded users for some groups. ok, one thing that i can say is the Samba 3 was VERY slow in comparence of Samba 2.2, when someone tried to enter a share it took allot of time until the share opened (could take like 15-20 secs, think what my boss told me when my server is working slow.....), in samba 2.2 it took less then a second (btw, the server is AMD 2600 XP). It looks like there was a problem with the password validations (didn't used smbpasswd), it took a lots of time to authenticate, but when i switched to smbpasswd it staied slow.... Well Pplz, tell me what you think... :-)
