Service "novell-named" (DNS server) fails to start

28-Jun-2010 12:02:52.938 general: main: notice: starting BIND 9.3.2 -u named

Resolution

  1. To create the missing CASA credentials, install the CASAcli client:
# zypper in casa-cli

  1. From the terminal do the following CASAcli commands to create the keys:
  • To store the proxy user and context:
# KEYVALUE=<your-dns-proxy-user's FQDN> CASAcli -s -n dns-ldap -k CN

Example:

# KEYVALUE=cn=OESCommonProxy,o=novell CASAcli -s -n dns-ldap -k CN

  • To store that proxy user's password in CASA:
# KEYVALUE=<proxy user's password> CASAcli -s -n dns-ldap -k Password

Example:

# KEYVALUE=abc123! CASAcli -s -n dns-ldap -k Password

  1. Verify that the "novell-xregd" service is running: rcnovell-xregd status
  1. Restart micasad: rcmicasad stop/start
  1. Start novell-named: rcnovell-named start

Cause

CASA was selected to be used to store the credentials of the dns-proxy user.
The CASA keys for the dns-proxy are missing.
CASA is selected by default and is recommend since it is more secure than using the file option.
