Description Mike McHenry 2001-11-08 22:18:12 EST
From Bugzilla Helper:
User-Agent: Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1)

Description of problem:
Most of the files placed in /etc/xinetd.d by various daemons have lines 

log_on_failure          += USERID

However, when connecting to any of these daemons from a machine without an 
identd daemon (Windows) you will experience a very long timeout while 
xinetd waits for a response.

This identd lookup is entirely unneccesary for anything useful and should 
not be introduced when 90% of the machines that are likely to connect to 
Redhat servers will not be running identd.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. Simply attempt to connect to a daemon such as imap or pop on a Redhat 
server from a client without an identd daemon.

Actual Results:  Long hang while identd times out

Additional info:

I would recommend completely revamping the necessary xinetd.d config files 
to NOT include USERID or somehow make xinetd timeout after a short 
interval (0-5 seconds) when an identd lookup is not available.

There is no good reason for the general case of client connections to 
experience a 30 second timeout because of an unneccesary identd lookup.

None of them are in xinetd - file them against the packages with this configuration.
