Subject [users@httpd] Re: [SOLVED] Apache-2.2 with LDAP authentication keeps spinning after authentication completes
Date Fri, 06 May 2016 01:28:21 GMT
Tried using (newer) web browsers under Mac OS X and no apparent
Read/Transmitting persistence is noted. So perhaps "the issue" is browser
specific (either OS or version). It would be nice to have a reliable way to
track this down with more specifics. Web browser console/error/debug windows
don't help. Packet capture mechanisms don't help, of course. Application log
files don't show anything, of course.

Subject: Re: [users@httpd] Apache-2.2 with LDAP authentication keeps spinning
after authentication completes

Another interesting observation: web browser (Firefox) continues to show
activity spinner and "read <hostname>" status (with AuthLDAP active at web
application initiation) even after the LDAP authentication is completed, the
OpenLDAP server is stopped, and the LDAP network connection is dropped. I can't
see activity status with the Opera browser, but the LDAP network connection
remains ESTABLISHED after terminating that web browser.

This appears to be an Apache(2.2) issue. Nothing in the Apache (HTTPD) log files.
