[Rommel Rodriguez Toirac]

***************************************
Hello Rowland;
thanks for write me back.

Is that first I had to join the PC to the domain :-O
Now it does work:

$ sudo net ads join -U Administrator
[sudo] password for administrator:  
Enter Administrator's password:
Using short domain name -- ATGTM00
Joined 'P107' to dns domain 'gtm.onat.gob.cu'

 Now verifying that everything was fine:

$ getent passwd ATGTM00\\rommel.rodriguez
rommel.rodriguez:*:11144:10513::/home/rommel.rodriguez:/bin/bash

$ getent group ATGTM00\\informatica
informatica:x:11142:

 It look tha be Ok; but when I try to login as a user of my network and is impossible.

If I try to add a user locally it is denied, because the user exists in Active Directory, and it is denied:

$ sudo useradd -c "Rommel Rodriguez Toirac" rommel.rodriguez
[sudo] password for administrator:  
useradd: el usuario «rommel.rodriguez» ya existe

How can i log in? What do I have to do?
