Opened: Sep 15, 2015 Severity: 3-Major
if /etc/krb5.conf edited manually the automated patching for the configuration file may behave wrong. For example, if file is cleaned up OR section [realms] deleted, then automated patching for the file will add realms records with each apd process restart /etc/krb5.conf grows in size with each apd process restart as a result krb5 library takes too long to parse the file and bigip stops processing requests
users cannot login if /etc/krb5.conf file size increased significantly. library cannot parse the file
/etc/krb5.conf file modified manually
Restore original default /etc/krb5.conf file. it will be patched properly at next apd process restart
krb5 patching functionality has been fixed.
