As a follow-up to STASH-3001 I want to report, that Bug STASH-3001 is not fixed for me (cannot reopen STASH-3001)

Randomly external tools (git clients: sourceTree, TortoiseGit) which try to access Repository on STASH server get access denied - as STASH is asking for CAPTCHA input. As I said this happens randomly - and is a big annoyance within our automatic build environment.

Within the administrative page http://stash:7990/admin/authentication, there is a checkbox available "CAPTCHA on sign up
Enables or disables CAPTCHA verification when a user signs up" - but this box (as well as the corressponding text) is greyed and CANNOT be checked. At the moment its NOT checked.
The "Maximum login attempts" currently is set to 100 ...

I do have full administration rights within STASH (System administrator)
