[feature-request] Add option to connect to LDAP account

[TheOneWithTheBraid]

An option to associate the Element login with the given LDAP account (presumed Nextcloud uses LDAP) would be great.

In my case I have a Matrix server and my Nextcloud connected to the same LDAP server. Adding this option, the users could be automatically signed in the Element app as soon as they open it.

An option in the admin configuration would be the way to implement it.

Such a single sign on would be great, but that probably need to be done differently as nextcloud doesn't store the user password and you can't retrieve it from LDAP. Perhaps something could be done by using nextcloud OAuth2 provider, but that would still require the user to go thru a few dialogs to authorize the matrix server.
