# This script is designed to print out a chart showing all zimbra COS and which servers are associated with each
#
# This script should run from the LDAP master replica in a multi-server install.
#
# Yes, this is a perl script that calls outside apps often.  It was the easiest way to interface to Zimbra.
#
# You will need to add your Zimbra mailbox server names as a regex string on line 58 in place of HOSTNAMEREGEX.  E.g.: hostname[1-6][0-9]
# You will need to add your Zimbra server names as a regex on line 61 in place of HOSTNAMEWILDCARD.  E.g.: hostname.*.domain.com
# If needed, you may want to adjust the printf formatting in the print* subs to better suit your naming convention lengths.
