Symptoms

Unable to change passwords on the Solaris system using Samba's Winbind for AD integration.

Trying to change the password for a AD user with Solaris "passwd" command fails :

$ passwd
passwd: Changing password for <AD-user>
passwd: User unknown: <AD-user>

Assumption about the configuration that can result in the error:

The system is configured so that AD users can login.

Specifically:

1) /etc/samba/smb.conf contains
    
     security = ADS
    
     idmap options are present
    

2) Using /etc/pam.conf-winbind as /etc/pam.conf


3) /etc/nsswitch.conf contains winbind in passwd and group

passwd: files winbind
group:  files winbind
hosts:  files dns
