I was able to move around some jar files and config files to finally be
able to run engine-manage-domains to add new domains. First I ran

#./engine-manage-domains -action=list
Manage Domains completed successfully

I did not get any domain, which makes sense since I only have default
setup. then I tried

#./engine-manage-domains -action=add -domain=bluepages.ibm.com
-user=snmishra at us.ibm.com -passwordFile=/tmp/.pwd

where /tmp/.pwd has my ldap password.

I got the following error -
Error: Authentication Failed. Please verify the fully qualified domain
name that is used for authentication is correct.. Problematic domain is:
bluepages.ibm.com Failure while applying Kerberos configuration.
Details: Authentication Failed. Please verify the fully qualified domain
name that is used for authentication is correct.

I also tried "-domain=bluepages.ibm.com:389"
