samba - Aug 2012 - Entrys in LDAP is not saving about the gecos

Hello !

I create one user with command: 

smbldap-useradd -a xbox -c "Game XBOX" -S "Sell games" -d
/home/xbox -s /bin/false


Then I type:
smbldap-passwd xbox #define password ldap user
smbpasswd -a xbox?? # create user samba

So. I can to make login in my domain. 

I check atributtes gecos is: SystemUser.

After I log in domain, in the top menu windows show:System User.

I changed this value gecos, but each login the gecos show System User.
It?s no changed never. 


This command in line 2, not define gecos, give default with "System
user".
If i change the value gecos in LDAP before te fist login, the gecos is with
value correct.
Any sugesstion ?

Thanks.
