Problems logging in to AMS on Amazon web services

Hi All

We've recently put an AMS server running CentOS together using the AMI # ami-ee7259ab for the US West region.

We're not able to log in to this machine.

We've put the following entry into ams.ini :

SERVER.ADMIN_USERNAME = admin

We have the following entry in users.xml

<User name="${SERVER.ADMIN_USERNAME}">

            <Allow>our hostname hhere</Allow>

            <Deny></Deny>

            <Order>Allow,Deny</Order>            <Password>d8f2d3ff51084c748a07cd516bd7fd704c55a90e07f700f92a4e474d9b512db5ed83da4bdf61b50f</Password>

        </User>

The password hash in the above XML was successfully generated using the command

./amsadmin -console -user admin

and we stopped the service before changing the password, then started it again.

We've even opened 1111 up to the world, and specified SERVER.ADMINSERVER_HOSTPORT = :1111 in ams.ini.

I still cannot log in. Does anyone have any ideas what we've missed?

Many thanks!
