Migrating authentication of Samba from smbpasswd to tdb

标签：

Was addicted various After you upgrade the OS of old Samba server. Put it also was using a set of 2.x era become 3.x is seems to have emerged.

Changes in 3.x

Format and location of the standard password file has been modified in 3.x.

 /etc/smbpasswd /var/lib/samba/passdb.tdb 

Also pdbedit command is provided for the administrator. And though it must have administrator privileges, and powerful general-purpose than smbpasswd.

Check the setting

by extracting a set of smb.conf in testparm command to confirm that the tdbsam is specified in the authentication DB.

 % testparm -s /etc/samba/smb.conf ... passdb backend = tdbsam ... % 

I make passdb.tdb from old smbpasswd file

Copy smbpasswd.bak to work for in the / etc and / var / backups.

 % sudo cp /etc/smbpasswd.bak /var/lib/samba/smbpasswd.txt 

I to convert pdbedit.

 % sudo pdbedit -i smbpasswd:/var/lib/samba/smbpasswd.txt \ -e tdbsam:/var/lib/samba/smbpasswd.tdb 

Retry fix the problem and get an error. This time I was simply remove the bad line.

 % sudo vi /var/lib/samba/smbpasswd.txt (remove invalid users) % sudo rm /var/lib/samba/smbpasswd.tdb (try again) 

I replace the password file.

 % sudo /etc/init.d/samba stop % sudo mv /var/lib/samba/passdb.tdb{,.bak} % sudo mv /var/lib/samba/{smbpasswd,passdb}.tdb % sudo /etc/init.d/samba restart 

To test if you can logon.

 % smbclient --debuglevel=3 //192.168.0.x/jdoe -U jdoe (jdoe‘s smb password) smb: \> exit % 

Troubleshooting

Really sure the user is registered.

 % sudo pdbedit -u jdoe -v 

To register it if it is not registered.

 % sudo pdbedit -a -u jdoe
