[Samba] Winbind / Samba auth problem after username change

Well, I always get 0 results, whether using cn, full username, wildcards, another existing and working user etc.

# cat /etc/passwd | grep 'ren_test'

returns nothing

# wbinfo -u | grep 'ren_test'

returns: ren_test4

I also created a backup of all those ldb files and restarted the samba service. Now there's no new sam.ldb but a file looking similar to it.

Here's the complete directory:

/var/lib/samba/private# ll

total 4644

drwxr-xr-x 4 root root    4096 Sep  7 14:38 ./

drwxr-xr-x 7 root root    4096 Sep  7 14:38 ../

drwx------ 2 root root    4096 Sep  7 14:39 msg.sock/

-rw------- 1 root root   24576 Sep  7 14:38 netlogon_creds_cli.tdb

-rw------- 1 root root 1286144 Sep  7 14:38 secrets.ldb

-rw------- 1 root root  430080 Sep  4 10:06 secrets.tdb

drwxr-xr-x 2 root root    4096 Jan 19  2016 smbd.tmp/

-rw-r--r-- 1 root root 1286144 Sep  7 13:09 *-tdb

Doing a ldbsearch on this file also returns 0 records. Even with the -a argument and no filter.
