Fixing erroneous SSSD.conf file header + QOL changes

[UndyingSoul]

Trying to get Truenas Scale LDAP to work with Authentik, I found a few issues in the sssd.conf template file, mainly the header being incorrect.

I also added some quality-of-life changes to help when debugging stuff like this.

Can one of the admins verify this patch?

This is as close as I got to getting Authentik to work with Truenas SCALE LDAP.

Still not mapping the email attribute, which makes sense since sssd doesn't support email.

It's also not mapping (on the UI) the groups a user is a part of. id <user> seems to have the right user groups, though.

Here's what I put in my Auxiliary Parameters section in the LDAP configuration.

# User attributes
ldap_user_name = cn
ldap_user_uid_number = uidNumber
ldap_user_object_class = user
ldap_user_shell = /bin/bash
override_shell = /bin/bash
ldap_user_extra_attrs = mail:mail # attempt at getting mail to work

# Group attributes
ldap_group_name = cn
ldap_group_gid_number = gidNumber
ldap_group_object_class = group

# Access control
ldap_access_filter = (ak-active=true)

# MemberOf Support
ldap_group_member = member
ldap_user_member_of = memberOf
