Re: [Radiusplugin-users] openvpn segfault when username contains space

[William Cooley]

I just found this post on the dev mailing list.
http://lists.gnu.org/archive/html/radiusplugin-devel/2009-02/msg00000.html
It's not clear if the username had the whitespace in the radius server 
or if the crash occurred when someone  accidentally added a space.
I just tried adding a space before or after the username and openvpn did 
not crash. So I'm guessing this occurred because the username had a 
space in the radius database.
