After running authconfig --kickstart --enablekrb5 the /etc/krb5.conf file is getting additional lines of data added to the bottom of the file

Solution Verified - Updated -

Issue

  • When I copy a krb5.conf file into /etc and run /usr/bin/authconfig --kickstart --enablekrb5 from a batch file or from the command line additional lines of data are getting appending to the bottom of the krb5.conf file.
  • While these changes do not break our authentication, they do modify our site approved krb5.conf.
  • The additional lines look like:
    • dc.example.com = dc.example.com
    • .dc.example.com = dc.example.com

Environment

  • Red Hat Enterprise Linux 6
