@kaucic: I used ADSI( Active Directory Services Interface) and even if i'm loggued as an admin I cannot see the userPassword field.
But I did some work with ADAM + Talend, and I got some troubles with user's insertion with a password.
The only I found is to used a LDAPS connection. I can insert an read all user's field
@shiny: the format of the dn is cn="yourcommonname",OU="yourOU",DC="yourDC"
