[Feature Request]: Explicitly request used LDAP attributes

[setpill]

Is your feature request related to a problem? Please describe.

When using so-called "operational" LDAP attributes, these are not returned by the LDAP server by default and need to be explicitly requested. This happens e.g. with attributes that can be used as "active" flags.

Describe the solution you'd like

Explicitly request all required LDAP attributes so that operational attributes become available.

Describe alternatives you've considered
