Urgent DSAPI Filter for Domino 6 Question

HCL Domino Domino Forum
1

Hello,

I have written a DSAPI dll which authenticates users against an external application. With Domino 5.0.x it works fine.

I have recompiled the dll with the new C API Toolkit for Domino 6 to verify the function under Domino 6.01. But on Domino 6 the dll has a curious behaviour.

Short explanation of the function:

If the user is authenticated against the external application, I return the following:

authData->authName=usersCanonicalName;

authData->authType=kAuthenticBasic;

return kFilterHandledEvent;

that works fine on Domino 5 and Domino 6

Now the part that causes problems on Domino 6:

If the user was denied from the external (authentication-)application, I return the following:

authData->authType=kNotAuthentic;

return kFilterHandledEvent;

(the user should got a new attempt to login via the standard login form) It works on Domino 5, but on Domino 6 the Domino Server returns nothing (http-Status 0 and no content).

Is there an expert who is experienced with the DSAPI and Domino 6? Or does anyone knows a workaround to avoid this curious (or standard?) behaviour?

Thanks for any idea

Timo

Subject: my friend George Chiesa from dotNSF is one of the most knowledgeable people about DSAPI I know

We do a lot of work together in this area and he did analyse the D6 version of DSAPI and we found a lot of differences.

If you need his contact details please send me a mail offline.

I documented “some” of this [in-]compatibility stuff between R5 and R6 DSAPIs in the recent Lotus Security Handbook SG24-7017.
