That error means that there is no registered proc with the name
"ad_verity_and_get_user_id" It could mean 1 of 2 things. Either
the proc doesn't exist at all or it could mean that the proc
exists but didn't get registered b/c there is an error within it.
In your case, the proc doesn't exist at all. I think it should read
set user_id [ad_verify_and_get_user_id]
(change the t to an f)
