Catalyst 4507R-E with Sup7L-E: SSO-Mode is possible with lanbase license

[pathoemmes]

Hello,

i've got a 4507R-E with two Sup7L-E and i thought, that SSO-Mode is only possible with ipbase- or enterprise license. So now i am wondering, that SSO-Mode is possible with lanbase license too. Is this a bug or a new feature :-)?

Based on the Release Notes for 3.11.X, no. NSF/SSO requires IP Base or Enterprise license.

Yes, based on release notes it shouldn't work, that was also my previous knowledge. So I was surprised that it works with lanbase. 

Kind regards
