Restrictions when logging in to a AR System server

The following restrictions apply to users logging in to a AR System server:

• Multiple IP addresses—With the exception of users who have Restricted Read licenses, non-administrative users can access a AR System server from only one computer at a time. This restriction applies to the server, not to an application. For example, if you run the BMC Helix ITSM on a AR System server, a user accessing any form in any ITSM application on that server can do so from only one IP address.
  
  AR System administrators (users who have the Administrator group in their Group List on the User form) can access a server from multiple computers simultaneously.

  AR System uses a globally unique identifier (GUID) to identify the computer, so users do not need to log in again if their IP address changes during a session.

• Wait time—After a user logs out of one computer, the user might need to wait a short time to make sure the status is cleared before using the same login name to access another computer.
• Session takeovers—A user who is blocked from access can perform a session takeover through a message dialog box. This can be helpful if someone forgets to log out of a client at a different location. Only one session takeover is allowed every fifteen minutes for each user.
• Matching user names—Multiple users with the same user name cannot log in concurrently if you use the User form for authentication. If you use external authentication, however, multiple users with the same user name can log in if they belong to the same groups. (In the cache, only one session is created, and this session is used for all users who have the same user name.)
