Fedora Core 5 Tomcat 4 problems

["Michael K. Smith" <mksmith@adhost.com>]

Hello All:

I am attempting to start Tomcat 4 using an rc script that uses the
unprivileged user "tomcat" to run the application.  The relevant line is:

su -l tomcat -p -s /bin/bash -c /usr/local/tomcat/bin/startup.sh

In addition, the tomcat user has /sbin/nologin in the password file.

Steps to make it work:

1) Set SELinux to permissive and reboot
2) Take resultant AVC messages and create local policy
3) Load policy, set SELinux to enforcing and reboot

If I leave SELinux in permissive the tomcat script works just fine and, if I
allow root to run tomcat that works as well.  I would like to have the
security of SELinux and an unprivileged user running Tomcat, so any help
would be greatly appreciated.

Below is a copy of the local.te file that was generated from the AVC
messages in /var/log/messages after setting to permissive.  The Tomcat
directory is /usr/local/tomcat and shows as:

drwxr-xr-x  tomcat   tomcat   user_u:object_r:usr_t
jakarta-tomcat-4.1.31

lrwxrwxrwx  root     root     user_u:object_r:usr_t            tomcat ->
/usr/local/jakarta-tomcat-4.1.31

Thanks in advance,

Mike
