As per samba upstream advisory:All versions of Samba prior to 4.16.x built with Heimdal Kerberos are vulnerable to an Elevation of Privilege attack. If the password of a user expires and need to be changed, a user could get a krbtgt using kpasswd with canonicalization turned on. The KDC should only provide a ticket for kadmin/changepw but returns a krbtgt. So a user could skip the password change and just use the krbtgt to get service tickets and use services in the forest.
