Description Soichi Hayashi 2012-02-21 19:39:00 UTC 
mod_nss RPM installs following directory 

2012-02-21 19:36:36 UTC [hayashis@soichi2:/etc/httpd/alias]$ ls -la
total 112
drwxr-xr-x 2 root root    4096 Feb 21 19:28 .
drwxr-xr-x 5 root root    4096 Feb 21 19:18 ..
-rw-r----- 1 root apache 65536 Feb 17 20:55 cert8.db
-rw------- 1 root root    4395 Feb 17 20:55 install.log
-rw-r----- 1 root apache 16384 Feb 17 20:55 key3.db
lrwxrwxrwx 1 root root      33 Feb 17 20:55 libnssckbi.so -> ../../..//usr/lib64/libnssckbi.so
-rw-r----- 1 root apache 16384 Feb 17 20:55 secmod.db

The fact that only group:apache can access the db means that mod_nss will not run if apache is configured to run under non-apache group.

The apache error log is overflowing with following message.

Not only mod_nss will not run, but it actually completely disables mod_ssl. I had to uninstall mod_nss in our system to get our system working again.
Comment 1 Matthew Harmsen 2012-03-21 21:09:17 UTC 
For the purposes of RHEL 5, we would like to suggest the following work-around:

    * cd /etc/httpd/alias
    * chgrp <non_apache_group> cert8.db key3.db secmod.db
