[Samba] passwd: Authentication token manipulation error

[Paul Matthews]

hi there,

I've got my RHEL4 Mail server authenticating against Active directory
using winbind.

When I login and try and reset my password using the 'passwd' command I
get this error message.

passwd: Authentication token manipulation error

Is there something i'm meant to do before I can change my ADS password on
a unix machine using winbind?

Can I?

here is my smb.conf file

workgroup = myodmain
security = ads
realm = MYDOMAIN.COM
encrypt passwords = yes

username map = /etc/samba/smbusers

winbind uid = 10000-20000
winbind gid = 10000-20000
winbind use default domain = yes
winbind enum users = yes
winbind enum groups = yes
template homedir = /home/%D/%u
template shell = /bin/bash
