Unable to add a user to the bucket

Howdy,

I am tried to add a new hire to one of the divisional buckets that use next cloud. The user is not found when adding them.

Also, when I do a user search, they are not found. However, when I do an Administrative → LDAP/AA Intergration → Login Attributes → “Test Loginname” it recognizes the user.

I am not an admin of this product, so I am not familiar with it, and I am probably missing something simple.
