 >> I'm running an INN 2.5.3 server, and I need to extend the timeout that
 >> nnrpd waits for a response from an external authenticator (e.g.
 >> ckpasswd). This seems to be hard-coded as 5 seconds.
 >>
 >> It looks like the relevant variable is tv.tv_sec, which is set to 5 on
 >> line 205 in auth-ext.c.

 > Yep, that's the hard-coded value.  A comment a bit above says:

 >> Can I simply increase this value and recompile to extend the timeout,

 > Just keep it under the value of clienttimeout in inn.conf (which is very

 include/inn/options.h.
