Last week I received a question from a new 10.1 NetScaler Gateway implementation that when more then 5 users where logged in on the CAG the following error was shown:
“Error: Login exceeds maximum allowed users”
But when you do a “show license” Maximum ICA users = “Unlimited” is shown.

These 5 users where using the 5 built-in platform licenses meant for SSL VPN/ MicroVPN and other nice things!
To resolve this issue if you are only using it for XenApp/ Desktop simply change the “Smart-Access Mode” to “Basic Mode” on the CAG vServer.
