Ok, 
try to redo:
problem:
We have debian 7 with samba pdc.

>From a joined ubuntu client( with winbind) , i can su for another domain user but getting other user:

root at blank005:~# su 59031614949
98121524292 at blank005:/root$

The numbers are usernames .

how can this happen?

# This can be either the interface name or an IP address/netmask;
# interface names are normally preferred
;   interfaces = 127.0.0.0/8 eth0

#### Debugging/Accounting ####

# that connects

# Cap the size of the individual log files (in KiB).
   max log size = 1000

# If you want Samba to only log through syslog then set the following

# should go to /var/log/samba/log.{smbd,nmbd} instead. If you want to log
# through syslog you should set the following parameter to something higher.

####### Authentication #######

# "security = user" is always a good idea. This will require a Unix account

# password with the SMB password when the encrypted SMB password in the
# passdb is changed.
