I suggest to check the pam-ldap config. IIRC it should be using the exop method to change password.

Hello all,
I have an LDAP server, that I use for system authentication, emails, etc, in a domain (homebox.space)
I have the password policies defined in the LDAP database, but they don't seem to apply to the users when changing a password.
Both "olcPPolicyDefault" and "olcPPolicyHashCleartext" are set up,
but
only the last is working, i.e. passwords sent in clear text by an
LDAP
client are automatically encrypted.
There is an overlay entry for the domain, example:
olcPPolicyDefault: cn=default,ou=pwpolicies,dc=homebox,dc=space
and a correct entry "pwdPolicySubentry" for each user.
However, when I try change the password with pam_ldap or using the roundcube password plugin, even the minimal length rule is ignored.

I have the whole source code here: https://github.com/ progmaticltd/homebox/
The Ansible tasks I am using to configure the LDAP server are here:

Any help welcome.
Kind regards, André Rodier.
PS: Merry Christmas / Happy new year / for those concerned.
