Hello everyone!,
I am trying to get my solaris 10 openldap 2.4.21 server to use my check_password.so module using the ppolicy overlay. When I try to change a user's password from a linux client, I get the following error message.
passwd ldapuser Changing password for ldapuser. Enter login(LDAP) password: New Password: Reenter New Password: LDAP password information update failed: Constraint violation Password fails quality checking policy passwd: Permission denied
Within my logs, I do not see any error messages from my check_password.so module. I created the directory /opt/openldap/etc/openldap/modules and placed my module in that directory and I added the modulepath in my slapd.conf.
Is there something I missed? Is this a PAM thing? I know this setup works on a OpenSUSE 11.2 openldap server. Help.
I included part of my slapd.conf, openldap configure, check_password.c source, makefile and ldd of my check_password.so.
Thanks!!!!
Jose Torres

I tried ppolicy_clear_txt I still have the same problem.

It seems to find the right libraries.
