ASA giving error "Clientless (browser) SSL VPN access is not allowed"

We recently switched to using Cisco AnyConnect VPN for our remote access needs, but I have a vendor that needs VPN access just to RDP into their server. I thought I would setup a Clientless SSL VPN just for them since they don't want to load any type of software on their PCs.

I've tried it manually and with the wizard and I get the above error. Config is below, and I'm using "dharrell" as my test account for the VPN.

In your Group Policy, do you have the VPN-TUNNEL-PROTOCOL set for webvpn?

Yes, it's there as well as SVC.

I'm not sure what I changed but now when I go to the url I get the login screen with the template changes I had made for the portal. However when I login it starts the anyconnect client.

Scratch that, I know what I did differently. I deleted the "dharrell" profile and added webvpn to another existing profile.

Good...   did that fix the issue then?

Nope, it still wants to install the anyconnect client once it passes the login stage.
These lines are telling it to auto install

 svc image disk0:/anyconnect-dart-win-2.4.1012-k9.pkg 1
 svc enable

You can remove those to disable that feature.

So if I remove the line "svc enable", how will that affect my VPN users who are connecting for the first time?

Those lines tell clients to download the image and run it if they don't already have it or if they have a lower version.

Well, I can't take it out of the config, as it appears my Anyconnect won't work properly....

Anyway to disable it for a single profile?
You would have to create a separate profile for this 1 connection.    Have that profile configured without the SVC image commands.    Since it is for 1 connection, you might want to use AAA local instead of passing it to another server group.   That way, that 1 id would be the only one able to use the profile.
