-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi : I am trying to strip some sort of prefixes out of the usernames using regular expressions in the hints file with no success in some cases. I have two scenarios with prefixes, where usernames can be received in the following form : Case 1. KNOWN_PREFIX/user@mydomain.com Case 2. KNOWN_PREFIX/RANDOM_STRING/user@mydomain.com In any of those cases, the username must be stripped, and only user@mydomain.com must be processed for AAA. I am using the "hints" file with an entry with a regular expression like : DEFAULT User-Name =~ "^(KNOWN_PREFIX/(.*/)?)+(.*@mydomain\.com)$" User-Name := "%{3}", Hint = "Stripped User-Name" The problem I'm having is that entry only works in case username comes with a form like case 2, I mean when username comes like "KNOWN_PREFIX/RANDOM_STRING/user@mydomain.com", the regexp works very well. But, when usernames comes as shown in Case 1 (KNOWN_PREFIX/user@mydomain.com), it gets a match in the hints, but username referred as %{3} gets a void value ( shown in the debug as ' ' ). It seems as if the conditional group "(.*/)?" in the regexp is causing something wrong in the next group reference but I'm not sure. Is this kind of regexp (the conditional one) supported in freeradius ?. Any ideas of what could be wrong ? Thanks in advance for any help.
