RE: OpenLDAP Issues
Hey Mike
Thanks for the response. When pam_password was set equal to md5 the only issue I had was with changing the password it was suggested that I switch to exop so I could use passwd to change the password instead of ldappasswd. With the password history and and strength testing I had testing this thoroughly with md5 and when I switched to exop I could see the attributes getting updated but I did not seem to matter. I think it is definitely something to do with the hashes. Here is the ppolicy lines in my slapd.conf file. Any other information I can provide just let me know.
overlay ppolicy
ppolicy_default cn=default,ou=policies,dc=turbocorp,dc=com
ppolicy_hash_cleartext
ppolicy_use_lockout
