Hi Calvin,

The issue is no so much what makedns -n will do , but how to actually create a 
CNAME record in xcat's DNS

Running nsupdate using a keyfile containing the key data that exists in both 
named.conf and in passwd tabdb, any change attempt results in :

; TSIG error with server: tsig indicates error
update failed: NOTAUTH(BADKEY

What I'm hoping to discover is how to add a record manually using nsupdate in 
the same manner as xcat does running makedns <node>.

I usually do something like this to get the TSIG auth key from the
xCAT passwd table, and use it to authenticate nsupdate:

$ xk=$(tabdump -w key==omapi passwd | awk -F, '!/#/ {gsub(/"/,""); print $3}')
$ nsupdate -l -v -y xcat_key:$xk

Hope this helps!

Cheers,

Kilian
