CentOS-7 (openLDAP using Webmin and PHPldapAdmin)

sndlt

I for the first time installed and brought up openLDAP and tools like Webmin and phpLDAPAdmin.

However, I can't seem to do anything with Webmin nor phpLDAPAdmin.

If I try to set up something like SSL certificate on Webmin, i get "Failed to generate certificate : Unsupported file or mode >OpenLDAP Server at WebminCore::/usr/libexec/webmin/web-lib-funcs.pl line 8733"

And the default login for phpLDAPAdmin that other guide websites have are not working. I apparently am doing something wrong.

Can someone please narrate some brief concise steps on what needs to be done to set up a very basic openLDAP server to manage with webmin and phpLDAPAdmin?

Thanks.
