Probably not. As Peter already said, how the binding works is
dictated by the spec, there's nothing to configure. <br>

All the front-channel SAML bindings use mandatory Base64 encoding
one way or another. It's inherent to the defined SAML 2 bindings.
So this is really a red herring.<br>

The most likely problem is you/they are using the wrong binding.
Looks like it's being delivered to the IdP's HTTP-Redirect DEFLATE
binding endpoint. If they're sending using the HTTP POST binding,
then they would need to use a different IdP endpoint. Or possibly
tell them (or configure if you have access) to switch to Redirect
binding - many vendors support a choice of either. Fwiw, the Shib
SP generally prefers the Redirect binding by default.<br>
<br>
The other likely problem is they simply have a bug in their binding
implementation. I don't know anything about them, but if their SAML
implementation is widely used, that's unlikely. But possible.<br>
