Maximum number of configurable RADIUS servers on Cisco IOS. Anyone knows?

A friend of mine raised an interesting question.

What is the maximum number of configurable RADIUS servers on Cisco IOS platform?

I failed to get this exact number after dozens of Google searching. Can any one help me about this? Thank you!

 

By the way, for Cisco NX-OS, the maximum number is “64”, which is described in documents like this one.

Resetting admin password to save my time re-installing Cisco ISE on VMware

Because installing Cisco ISE 1.0 on VMware takes over 30 minutes, it is a natural choice to let the fresh installation run overnight.

When I come back in the morning, I found myself locked out even using default “admin” password “cisco”, when I try to log into the web interface. The error just showed something like “Account has been disabled …”.
