using maui 3.3

n support of our moab cluster moving to an allocation model using
gold we setup gold to use HMAC to talk to moab and maui.

While moab is working fine gold is rejecting responces from maui with
the error:

04/30 13:23:36 MSURecvPacket(9,BufP,256,NULL,15000000,SC)
04/30 13:23:36 WARNING:  request failed
04/30 13:23:36 ALERT:    request failed with status code 424 (Failed
authenticating message: (Message not signed -- No signature found).)
04/30 13:23:36 MSUDisconnect(S)
04/30 13:23:36 ERROR:    cannot receive response from allocation-
manager server 'cac-admin01.engin.umich.edu':7112
04/30 13:23:36 MSysRegEvent(FAILURE:  cannot receive response from
allocation-manager server cac-admin01.engin.umich.edu:7112 (cmd:
'<XML>')
,0,0,1)


This is correct looking in the gold logs there are no <SignatureValue>
entries in the XML to gold.

We have in maui-private.cfg:

CLIENTCFG[bank] CSKEY=SecretKey CSALGO=HMAC64

(also tried just HMAC)

In maui.cfg:
AMCFG[bank] TYPE=GOLD HOST=cac-admin01.engin.umich.edu PORT=7112
CHARGEPOLICY=DEBITALLWC JOBFAILUREACTION=NONE TIMEOUT=15
WIREPROTOCOL=XML SOCKETPROTOCOL=HTTP

Any help on this would be great.
