LDAP/AD accounts: Files cannot be shared with users containing umlauts (ä,ö,ü) in their displayName #27958

Closed m8ichael closed 3 years ago

m8ichael commented 3 years ago

Steps to reproduce

  1. Create a new user in AD containing an umlaut in the distinguishedName (=User A)
  2. Create a second user in AD (=User B)
  3. Deactivate in the nextcloud settings the autocomplete function of usernames
  4. User B should try to share a file with User A
  5. Even if the name of user A is typed completely, you aren't able to share the file with user A

Expected behaviour

You should be able to select user A to share a file with him.

Actual behaviour

Nothing happens
