Hello,

I see there are more specific threads discussing the upcoming changes to Active 
Directory[1] (patch tuesday update this fall) for LDAP signing[2] and LDAP 
enforce side channel binding[3] that is coming?

Is there an active working group in the SSSD team evaluating this change and 
its impact in general?  For the AD form of SSSD integration, is there an 
indication of what the impact there is for these changes, for SASL based 
authentication configurations?  Or the impact to startTLS based configuration?

Are there already updates to SSSD planned/coming/released that are addressing 
these changes?

authentication.
