A user exists and is available in mattermost for (e.g.) Direct Messages, but does not appear in the search results when trying to add the member to a channel (public or private).
Steps to reproduce
Not sure how to reproduce. We are using the following versions. Most of our users authenticate via LDAP through gitlab.
(Updated per suggestion)
Mattermost Version: 5.23.0 Database Schema Version: 5.23.0
I expect to be able to add any existing user to any channel.
The user is not found in the search results (but other users are), and so cannot be added to a channel.
