license - no of licensed sessions clarification

for a 2 user license, after importing the customer license it actually shows Licensed Sessions as 3 . but when 3 users login concurrently system prompts an error msg like ‘ur license does not allow more than …etc etc.’

so i wanted check what is the 3 rd license is used for.

Is it used for the nabision server?

we are using NAV 5.0


your license only allow 2 sessions at one time…

you couldn’t login more than that

The 3. license if for the NAV 5.0 Application server. When you start the nas.exe, then the last session is taken.
