Which FAQ?

I won't have all the details anymore and it would probably just be a list of "how-not-to-do-this" examples anyway. What happened was that nothing changed and the errors reported the same issue.

I just need one way to get rid of the host/ portion. The old server uses an attr_rewrite module but that is now deprecated.
This is what the old server uses:
attr_rewrite findthewlan {
attribute = Called-Station-Id
# may be "packet", "reply", "proxy", "proxy_reply" or "config"
searchin = packet
searchfor = "(^.*:)(.*)"
replacewith = "%{2}"
ignore_case = no
new_attribute = no
# max_matches = 10
# ## If set to yes then the replace string will be appended to the original string
append = no
}
attr_rewrite copyusertocertcn {
attribute = Cert-CN
new_attribute = yes
searchfor = ""
searchin = packet
replacewith = "%{User-Name}"
}
attr_rewrite removehostportion {
attribute = Cert-CN
# may be "packet", "reply", "proxy", "proxy_reply" or "config"
searchin = packet
searchfor = "(host/)(.*)"
replacewith = "%{2}"
ignore_case = no
new_attribute = no
# max_matches = 10
# ## If set to yes then the replace string will be appended to the original string
append = no
}

No. Does it even need to be there?
> Can you think of any way to copy the User-Name to another attribute? Perhaps with editing?
You've lost me. Why would I want to copy the User-Name to another attribute? What am I achieving?
> The server comes with extensive documentation and debugging. This problem *is* solvable, if you follow a careful process.
I'm doing my best and still getting lost. There might be extensive documentation but I haven't yet found what I'm looking for.
