Are you suggesting that using a prefix domain like that will cause problems, or
that I should be using the realms module?
I have no problem with using the module, as it's worked well for the proxying
side of things, but I need to be able to authorize the users on our domain, and
that means I need to get a stripped username and pass it to the DB. I'll poke
at it and see if I can get that side working.

It seemed like a good idea at the time.

This works a little better:
elsif("%{User-Name}" =~ /^(.*)\\\\?(.*)$/){
update request{
Stripped-User-Name := "%{2}"
}
}
But gives this:
(5) ? Evaluating ("%{User-Name}" =~ /^(.*)\\\\?(.*)$/) -> TRUE
(5) ? elsif ("%{User-Name}" =~ /^(.*)\\\\?(.*)$/) -> TRUE
(5) elsif ("%{User-Name}" =~ /^(.*)\\\\?(.*)$/) {
(5) - entering elsif ("%{User-Name}" =~ /^(.*)\\\\?(.*)$/) {...}
(5) update request {
(5) expand: %{2} ->
(5) } # update request = updated
(5) - elsif ("%{User-Name}" =~ /^(.*)\\\\?(.*)$/) returns updated
(5) - if ("%{User-Name}" !~ /^.*\/.*$/) returns updated
....
(5) sql : expand: %{Stripped-User-Name} ->
(5) sql : sql_set_user escaped user --> ''
Not sure what I should be doing there. Changed it to %{0} and also to %{1} and
both gave me hokies\dawson, which was at least successfully written into
Stripped-User-Name.
Would love some more insight into how unlang handles these things, as I'm sure
we'll run into a use for it in the future, even if I manage a realms-based
solution to this.
Thanks much,
