Kurt--

Yes, you are correct.  I get the same behavior with ldappasswd.  I'll post 
this to PADL's list & thank you for the reply.

Re: ACLs and password policies






The problem, despite return of insufficientAccessRights
result code, appears (by my quick examination of the
overlay code) to have nothing to do with access controls.
It appears that an administrative policy was not adhered to.
In particular, as indicated by the additional text provided
with the result code, the client did not provide the old
password.

You should be able to duplicate this behavior using
ldappasswd(1).

You likely should consult the documentation of the LDAP
client software you are using to not only determine its
capabilities, but how to make use of those capabilities.
(Please use PADL-provided mailing lists to discuss issues
specific to PADL software.)
