[Samba] Strange problem with pdbedit -Lv : missing users ?

Dear Gaiseric, 

Yes, according to testparm the backend is a plain text file : 

 smb passwd file = /etc/samba/smbpasswd
 passdb backend = smbpasswd 

Therefore I wonder where the User SIDs are stored ?! 

About "getent passwd", yes all users (active users at least) have a Unix

About the users that are missing in pdbedit, there is not error in
smb.log when they log in. (But I haven't set loglevel to debug) 

To create user we are using Unix "useradd" and Samba

(smbpasswd) a) If I do : tdbdump schannel_store.tdb dump | grep BWPC |grep SECRET | wc I get 95 machines (this number looks good). b) smbpasswd is a text file that looks good. c) I can also do "tdbdump secrets.tdb dump" Thanks a lot in advance for any advice, Denis Le 15.12.2014 22:00, Gaiseric Vandal a écrit : What is the backend ? Can you use tdbdump to dump out the local account info from samba password file?

Strangely, all these missing machines and users are working perfectly well. The problem is that I need to get their SID to be able to migrate to a new serve
TECHNICAL DETAILS : * Samba 3.3.10 * Number of machines : * Unix : 128 machines * pdbedit -Lv | grep "Unix" | grep "$" | wc : * 13 machines only * Number of users : * Unix : 79 domain users * pdbedit -Lv | grep "Unix" | grep -v "$" | wc : * 52 users only ! To be honest I don't absolutely need pdbedit to work, if I can list the SID of all users by some other mean, it will be OK. Any help would be greatly appreciated. Denis P. S. I saw somewhere that it could be due to missing Unix users, but these users are not missing.
