Users unable to reset AD passwords through CAG

I have a client that has a Citrix Access Gateway (5.0.1) installed. When users passwords expire in AD they are prompted t0 reset them:
change expired passwordWhen the user goes through the motions they get:
error
So I thought, oh yea, CAG isnt talking to DC on port 636 and using standard unsecure LDAP on 389. I was wrong:
cag ldap
So I looked at the CERTS and it seems like all the relevant certs are there:
certs
If I go into that users account and set it to never expire, they can log on fine so I know that secure LDAP is working over 636.

Im at a complete loss.

Any ideas?

Thanks

Hi.

Servers with Network level authentication enabled pose this problem even to native Microsoft RDP clients. Please disable nla for a test.

Ok, no further idea here.
You should contact Citrix support if possible.

Tried Citrix support and they no longer support our CAG. Their recommendation was to upgrade to a Netscaller. Client doesnt have £8K to spend on that just to allow users to reset their AD passwords so really need to find a way to allow this.
