Hello Alexander, hello Nadav,

Thanks for the input. I took a note about LDAPS too. Radiator uses 
Net::LDAP which in turns IO::Socket:SSL which can do OCSP. It might be 
that Net::LDAP requires updates to enable OCSP for LDAPS or LDAP with 
Start TLS. We'll need to take a better look at this.

We have done some work with EV but have not used it within Radiator.

With Radiator there's the possibility of using SQL or LDAP libraries 
that support asynchronous operations which is probably a better fit with 

Related to this, AuthBy RADIUS and its subclasses already support new 
return code (ASYNC) which allows an AuthBy to tell Handler that there is 
an asynchronous call in progress. In case of AuthBy RADIUS, when the 
reply is received, Handler can now move to the next AuthBy when there 
are multiple AuthBys. In other words, AuthBy RADIUS can work like the 
other AuthBys in a stack of AuthBys.

Previously there were two choices:
o the default which is that AuthBy RADIUS returns IGNORE when it has 
proxied the request
o Synchronous flag which tells AuthBy RADIUS to wait for the reply 
before moving on.

Thanks for your input,
