LDAP's Verify Connection times out faster than listed

While testing NEXUS-8606, I went back to a branch before the changes to establish how LDAP was running in NX3 (and NX2) pre-change to review for regression issues.
When testing NEXUS-8606, I noticed that when I set the Connection Rules (via the Connection "tab") that it timed out within a 7 count when I clicked "Verify Connection" regardless of what I put in that field.
In the branch I tested before NEXUS-8606 (109941d), Verify Connection seemed to take longer (or shorter) as I adjusted the values.
Note, in order to see this, you need to do a bad configuration. If you have a good configuration it works immediately.

Honestly, I am not even sure it's supposed to work this way (or if it was only for actual LDAP timeout).
These fields are new to NX3 (so not NX2 regression). I did not check older NX3 milestones at this time.
