Increase concurrent logins?

Hi all,

I've been tasked to create a robot account across a bunch of SunOS servers, amongst the requirements for this account is this condition:
Concurrent access requirement

  • The robot account shall have the ability to create at least ten(10) concurrent access sessions. In order to faciliatate this, the concurrent access attribute shall be set to 10.

I have no clue what "attribute" they are referring to, and haven't been able to turn up much on the google or searching the threads here. I don't know how many concurrent sessions Solaris will let you have by default either. Anyone know much about this?
