AAA Client Handler: Found extended error code 589827, ReqType 16386 request /AGServices/discover

[RobinM]

I receive the error message AAA Client Handler: Found extended error code 589827, ReqType 16386 request /AGServices/discover when trying to connect (SSO) through the Citrix Workspace App to the Citrix gateway which is configured with an authentication profile which has an advanced LDAP authentication policy bound to it. When I bind a basic LDAP authentication policy to the gateway using the very same LDAP action/server then everything works fine. What am I missing here?

Thanks in advance!
