Hi all,

Usage freeradius 2.1.2 and i'm with problems about username authentication.

Simply authentication accept any variations of the same username. Example:

Register user: "var"

Is accept:

"Var" "vAr" "vaR" VaR" "VAr" "vAR" "var " ...

This ends "bypassing" the blockage i do for multiple sessions with the same user. ( attribute Simultaneous-Use )

I noticed that the file /path/freeradius/policy.conf have the function with filters if to solve problem, but not function.

The unique that works is filter space start.

filter_username {
                # spaces at the start: reject
                if (User-Name =~ /^ /) {
                        reject
                }

                # spaces at the end: reject
                if (User-Name =~ / $$/) {
                        reject
                }

                # Mixed case: reject
                if (User-Name != "%{tolower:%{User-Name}}") {
                        reject
                }

        }

Appreciate the help.
