Mixed-case usernames break user portal permissions

[mrmarkuz]

When the openldap "administrator" user logs in using a capital letter in the name like "Administrator" he can login but doesn't have the permission to see the "Users & Groups" entry.
Also a user "Foo" (capital "F") that's member of the domain admins can't see the "Users & Groups" when logged in as "foo" (lower case)

Steps to reproduce

• Create openldap user domain
• By default a user "administrator" (lower case) is created
• Login to the user portal as "Administrator" (first upper case capital)

Expected behavior

The logged on user can see the "Users & Groups" menu as he is in the domain admins group.

Actual behavior

The logged on user can't see the "Users & Groups"

Components

• core 3.8.0
• openldap 2.3.1

I cannot reproduce to create from the cluster-admin interface a user Foo, I got a validator stop, the upper case are not allowed. How did you create the user Foo

Validation errors: [user: Does not match pattern '^[a-z][-._a-z0-9]*$']

QA

verify the bug is not more reproducible with ghcr.io/nethserver/openldap:2.3.2-dev.1

using Administrator or administrator allows to get administrative permission in the user-panel
