When these packages are installed, during login to the hotspot ROS crashes.
Will open bug report.
Are you using a SSL login page? If so, take a look at this post:

Does any of that sound like your problem?
I am not using SSL, just the standard login page from MikroTik, which is CHAP, I guess.
Disabling/removing package “User-Management” solves the problem.
Sounds like a memory problem. What type of device is this running on?
Celeron, 500Mhz, 256MB.
