LDAP Password changing

[Neil Marjoram <n marjoram adastral ucl ac uk>]

Can anyone help me with changing passwords in an LDAP database ? 

I have set up a proxy user with write access to the database, but I
think the error is client side and lies somewhere in the PAM config.

The error I receive is :

bash-2.05b$ passwd
Changing password for user testuser.
passwd: Authentication token manipulation error

The same error occurs if I use root to try and change the password.

I have the /etc/ldap.conf set correctly with /etc/ldap.secret containing
the proxyuser password.

I get no output to the syslog on the client.

I get this out in the slapd log file :

The /etc/ldap.conf is correctly set.

Thanks for your help,


Neil.
