[Samba] Samba authentication slow after upgrade to Samba 3
Hi, I have just upgraded a server from Samba 2 to Samba 3 and some of the Windows clients are taking a long time to authenticate shares (1 or 2 minutes). Eventually the username/password box appears and then when you enter a correct password, all is fine - it is just the initial authentication. This is a simple UNIX password Samba server (with NIS) and I have set it to not use encrypted passwords. I get these errors, repeatedly, in the messages file: [2007/06/01 08:29:26, 2] auth/pampass.c:smb_pam_auth(514) smb_pam_auth: PAM: Athentication Error for user mcr3 [2007/06/01 08:29:26, 2] auth/pampass.c:smb_pam_error_handler(73) smb_pam_error_handler: PAM: Authentication Failure : Authentication failure [2007/06/01 08:29:26, 0] auth/pampass.c:smb_pam_passcheck(810) smb_pam_passcheck: PAM: smb_pam_auth failed - Rejecting User mcr3 ! Here is my testparm output: # Global parameters [global] workgroup = DFGSRV server string = dfgsrv Samba Server %v encrypt passwords = No password level = 8 username level = 8 log level = 2 log file = /var/log/samba/%m.log max log size = 200 deadtime = 30 socket options = SO_KEEPALIVE SO_BROADCAST TCP_NODELAY IPTOS_THROUGHPUT dns proxy = No idmap uid = 16777216-33554431 idmap gid = 16777216-33554431 cups options = raw oplocks = No level2 oplocks = No [homes] comment = Home Directories read only = No create mask = 0664 directory mask = 0775 Any help gladly received as it is taking some of my users half an hour to disconnect from their previously mapped shares and to reconnect to them. The problem persists if a user logs out and back in again and after a Windows client machine reboot.

[Samba] Re: Samba authentication slow after upgrade to Samba 3
I have a gut feeling that this is to do with encrypted passwords. I have "encrypt passwords = no" set and pc's have the clear text password hack - could this be causing it? I really don't want to go t encrypted passwords if I can help it as it will mean another password file to keep in sync. Regards Gary

[Samba] Samba authentication slow after upgrade to Samba 3
This is really frustrating me - I cannot seem to resolve the problem. Some users can connect no problem and others take a long time. The users that take a long time leave lots of entries in the messages file: Jun 5 13:00:33 dfgsrv2 smbd[9148]: [2007/06/05 13:00:33, 0] auth/pampass.c:smb_pam_passcheck(810) Jun 5 13:00:33 dfgsrv2 smbd[9148]: smb_pam_passcheck: PAM: smb_pam_auth failed - Rejecting User rma !
