kerberos_selinux: Security Enhanced Linux Policy for Kerberos.
NAME
kerberos_selinux - Security Enhanced Linux Policy for Kerberos.
DESCRIPTION
Security-Enhanced Linux secures the system via flexible mandatory access control. SELinux policy can be configured to deny Kerberos access to confined applications, since it requires daemons to be allowed greater access to certain secure files and additional access to the network.
BOOLEANS
You must set the allow_kerberos boolean to allow your system to work properly in a Kerberos environment.
setsebool -P allow_kerberos 1
system-config-selinux is a GUI tool available to customize SELinux policy settings.
