|
| For all you radiusd hackers:
|
| In the routine unix_pass() in radiusd.c, there's an unnecessary call to
| getpwnam() if you're using shadow passwords. getpwnam() is called only
| to check that the password field is "x", which it always should be.
|
| getpwnam() is relatively expensive on a huge password file.

I know this thread is a little stale, but I never saw any
mention of the fact that AIX, OSF, Ultrix and DYNIX/ptx have a hashed
/etc/passwd option. (Maybe it isn't even worth mentioning). This
eliminates big search times for getpwnam(). SunOS 4&5, HP-UX 9&10 and
IRIX don't seem to have it, though. Or has someone found that they do?
