F26 KMail IMAP & GSSAPI: Asks for Password??

I've been using KMail with Akonadi/IMAP for a number of years and have been able to use GSSAPI authentication without issue at least back through F23. After upgrading to F26, KMail now asks for a password every X minutes. Without entering a password, I click "Ok" and it proceeds to retrieve my email. My Cyrus logs indicate I logged in with GSSAPI. Has anyone else run into this sort of thing? Thanks. -A -- Anthony - https://messinet.com/ - https://messinet.com/~amessina/gallery F9B6 560E 68EA 037D 8C3D D1C9 FF31 3BDB D9D8 99B6
