You can optionally specify a value for the testUser parameter. The testUser must be a valid user on LDAP and in the given base context DN.
When you specify a value for testUser and then select Apply, Avaya Aura® Device Services validates the following in the LDAP:
That the user is searchable with a given base DN and search filter.
The group to which the user belongs — user, administrator, or auditor.
The values for Role Attribute ID and Role Name Attribute.
The Last Updated Time attribute, role filter syntax, and active users search filter syntax.
