Session size garbage after an AD query, can I remove them?

Hi Samuel,
I think the easiest option would be to have it populated in AD and use query to get the AD variable.
There's a way to unset session variables, but it may require a lot of customization to match your case, discussed here https://community.f5.com/t5/technical-forum/how-to-delete-apm-session-variable-from-another-session/m-p/250353
