kerberos oddities

i was forced to do a complete reinstall of 10.3.4 server over the weekend... now kerberos acts a little weird. on my previous installation, i did not have dns setup, so kerberos needed to be setup manually and worked great. with the new install - kerberos "just worked" after setting up dns and promoting to a od master. :) first, i noticed that when my hostname from localhost to myserver's name, during the periodic daily mainetence - i would get errors saying kerberos couldn't bind to port 749 - address already in use, etc... i had to change the watchdog.conf to - # DEFAULTS #kadmind:respawn:/usr/sbin/kadmind -passwordserver #kdc:respawn:/usr/sbin/krb5kdc #NEW kadmind:respawn:/usr/sbin/kadmind -passwordserver -nofork kdc:respawn:/usr/sbin/krb5kdc -n this fixed that problem, but now i am getting multiple tickets issued to me for krbtgt and imap for the same user, is this normal behavior?
