User Management: Make "Display Name" for LDAP-Users non-editable

[johkoenig]

Steps to reproduce

1. Login to Nextcloud as Administrator, go to Users
2. Try to change name of LDAP Users

Expected behaviour

Field is read-only or not readable at all (just a string).
This may apply to other forms of external authentication also (e.g. OAuth, not tested).

Actual behaviour

You can type in a new display name.
Information seems to be not saved, on next page reload, old name apperars.

Server configuration

Nextcloud version: 14.0.3

Thats a bug, not an enhancement. LDAP display name is built from LDAP information, so theres no point of having an editable field. Please put the "bug" label to it.

Our OCS user endpoint returns the backend string per user, but not the backends capabilities. We'd need to extend this first, and then deal with those values in the user settings frontend. cc @skjnldsv
