Exception: Argument 2 passed to OCA\User_LDAP\Group_LDAP::_groupMembers() must be of the type array or null, string given #27606

How to use GitHub

Steps to reproduce

I've seen this in a couple of places but it's most obvious in the following way:

  1. Install the Deck App
  2. Setup LDAP including group membership and nested groups
  3. Share a Deck board with an LDAP group

Expected behaviour

The board should open.

Actual behaviour

The board spins forever with a 500 error in the console, and the following stack trace in the logs:

[deck] Error: Exception: Argument 2 passed to OCA\User_LDAP\Group_LDAP::_groupMembers() must be of the type array or null, string given, called in /var/www/html/apps/user_ldap/lib/Group_LDAP.php on line 283 at <<closure>>

   OC::handleRequest()

GET /apps/deck/boards/5
from {Redacted IP} by {Redacted User} at 2020-12-01T17:29:17+00:00

This exception seems to be caused by:

I believe had the same issue, although I did not need to install any additional app. User membership under [Users -> Everyone] was displayed correctly due to the LDAP server memberOf overlay, which resolves group membership recursively. When displaying the individual groups under [Users -> ], however, the list was empty and the error described above was logged. This issue stopped showing up on NC 20.0.5 when I disabled nested groups, so the problem seems to be in the algorithm that recursively resolves the members. In case it's relevant: I'm using FreeIPA as a backend (389 DS LDAP server).

The upper part of the stack trace looks unrelated to deck, as we there only call to get all users of a group, so maybe this rings a bell for @blizzz

Is this Issue still valid in NC21.0.4? If not, please close this issue. Thanks! :)
