LDAP issue with SASL 2.1.26

[Sergey Emantayev]

Hello,

We successfully use OpenLDAP C SDK 2.4.36 integrated with Cyrus-SASL 2.1.23. Recently we have upgraded Cyrus-SASL to 2.1.26 and encountering the next issue.
 
LDAP search consistently fails. We analyzed this issue and found the following behavior.
 
When we use OpenLDAP with Cyrus-SASL 2.1.23 the LDAP Message Search Request payload is wrapped in GSS-API payload.
 
When we use OpenLDAP with Cyrus-SASL 2.1.26 the LDAP Message Search Request payload is not wrapped in GSS-API payload at all. LDAP Search Request looks like clear text LDAP Search Request and not like LDAP SASL Search Request.
 
In both cases - with Cyrus-SASL 2.1.23 and with Cyrus-SASL 2.1.26 – LDAP SASL Bind succeeds and LDAP SASL bindResponse looks identical with Cyrus-SASL 2.1.23 and with Cyrus-SASL 2.1.26.

Please advise how to troubleshoot the issue.

Thanks & Regards,
Sergey
