Steps to reproduce

1.Create a user named user1 and another user named u2 (with a username (Display name) of 2 or fewer characters).
2.Log in as user1 and share a password with u2 in Passman.
3.Observe that: u2 appears in the search results but is marked in red and cannot be selected.


4.Rename u2 to user2 (or any username (Display name) with more than 2 characters).
5.Retry sharing the password with user2. Sharing now works as expected.

Expected behaviour

Password sharing should work regardless of the recipient's username (Display name) length.

Actual behaviour

Password sharing fails when the recipient's username (Display name) is 2 or fewer characters. The user is marked in red and cannot be selected, even though they appear in the search results.
