No. It wouldn't. Because the User-Name is already set, the '=' operation does nothing. Using ':=' instead will overwrite the existing value in the session-state.

But, like Alan D says, it's probably best to use your own internal variable (such as Inner-User-Name as per his suggestion) to store the username independently of the session-state one set from the outer session. :-)

> We don't want to cache the VLAN number itself, i.e. don't want to make the VLAN decision in the inner post-auth but we do want to cache the inner User-Name so it can be easily accessed later to do the VLAN calculation on resumed sessions.

Which is fair enough.
