Error: Call to a member function instanceOfStorage() on null ( with LDAP, NC16 )

[andrewborell]

Get this error using fulltextsearch and file scan if I change a users first or last name in LDAP and it syncs across thereby leaving parts of the old accounts behind in nextcloud. I suspect I should be able to merge the accounts to fix the problem and will test this today.

I found the issue is that when a users name is changed in LDAP it creates a new link in the ldap mapping in nextcloud but the old user is never cleaned up in the groups. When doing a file scan there is no issue but fulltextsearch chokes on the orphaned user in the group. I think this must also be tied into group folders. Since there are 4 places this is tied into I will leave it to the admins to triage this matter.

Here is a stack trace:

Mind to add the https://github.com/nextcloud/server/blob/master/.github/ISSUE_TEMPLATE/Bug_report.md to your post?

cc @nextcloud/server-triage Hmm. We have fulltextsearch, ldap and groupfolders.
