Hello,
I just came across this: "While Active Directory permits SASL binds to be performed on an SSL/TLS-protected connection, it does not permit the use of SASL-layer confidentiality/integrity protection mechanisms on such a connection." (http://msdn.microsoft.com/en-us/library/cc223507.aspx).
Could this be my issue? Is there a way to turn off the SASL-layer confidentiality/integrity protection mechanisms when I use openLDAP?
Thanks, Kris

Thanks for letting me know that it's an ok use case.
The back end is AD, but it is a "black box" to me. I have access, but the event viewer is empty. It does work if I use Kerberos only or TLS with simple bind through. Is there anything you can suggest that I can do on the server side to show me what it may be complaining about?
Thanks for your help! Kris

Is the usecase of SASL authentication with Kerberos to the LDAP server and TLS to the LDAP server for all other communication a valid one?
Certainly it is valid, and has worked in the past. Just keep in mind that what you've described here is SASL/GSSAPI + TLS on the same session. Not all LDAP servers support that, M$ AD is known to have failed on that in the past. It has been tested to work fine in OpenLDAP before.
I have not personally tested with the version of Cyrus SASL and Heimdal Kerberos you mentioned, so no comment on the current state of things.
Thanks, Kris

Apparently I can't read my own bug reports. This may or may not beyour issue.
