Really depends on what your needs are.<div><br></div><div>You could have one cert per user, and use the same authentication information in your rabbit cloud for all users. I just noticed however that the erlang new_ssl implementation does not support CRLs, so you won't be able to revoke a certificate and have that reflected by an authentication failure on the rabbit server.</div>
<div><br></div><div>Wonder what the odds of adding CRL or OCSP support to rabbit are....There was a thread about this in 2009:�<a href="http://lists.rabbitmq.com/pipermail/rabbitmq-discuss/2009-July/004189.html">http://lists.rabbitmq.com/pipermail/rabbitmq-discuss/2009-July/004189.html</a></div>
<div><br></div><div>Both these functionalities are pretty trivial to implement using the openssl library</div><div><br></div><div>So I guess my original suggestion doesn't fly as a good solution, sorry!</div><div><br>

your app use the current credentials of the user to grab the certificate and

<p class="MsoNormal"><span style="font-size:9.0pt;color:navy">We have a number of Windows users who want

SSPI authentication to allow clients to connect? This is surely a common
challenge, particularly in an organisation where there are large numbers of

systems is hugs.</span></p>
