Dynamic session timeout

[Sam T]

Hi!

Thanks again for the help! the year 2000 was us playing with dates to see
if we can learn about out issue. We are getting this error:

Improperly nested variable; %{integer:reply:WISPr-Session-Terminate-Time}}
rlm_expr: xlat failed.

We have some syntax issue.

Your advise is very helpful!

User-Password in the request is correct.
