From 638eae0dfb2cf33d58eccca371a8dc98881cc5af Mon Sep 17 00:00:00 2001 From: Sheogorath Date: Sat, 17 Mar 2018 21:56:52 +0100 Subject: Add check for undefined UUID This check is needed at there are tons of LDAP implementations out there and none has at least one guaranteed unique field. As we currently check three fields and added an option to select one yourself, it's still not said that any of these fields is set. This will now create an error and fail the authentication instead of letting people may get access to other people's notes which are stored under a this way deterministic wrong userid named `LDAP-undefined`.
