Maybe the information I collected here https://bugzilla.mozilla.org/show_bug.cgi?id=1734791 for the Firefox snap, which suffers from the same problem, is helpful in order to fix the problem for the Chromium snap as well.
** Bug watch added: Mozilla Bugzilla #1734791 https://bugzilla.mozilla.org/show_bug.cgi?id=1734791 -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to chromium-browser in Ubuntu. https://bugs.launchpad.net/bugs/1849346 Title: [snap] kerberos GSSAPI no longer works after deb->snap transition Status in chromium-browser package in Ubuntu: Confirmed Status in thunderbird package in Ubuntu: Incomplete Bug description: I configure AuthServerWhitelist as documented: https://www.chromium.org/developers/design-documents/http- authentication and can see my whitelisted domains in chrome://policy/ but websites that used to work with SPNEGO/GSSAPI/kerberos no longer work. I'm guessing the snap needs some sort of permission to use the kerberos ticket cache (or the plumbing to do so doesn't exist...). I can confirm that Chrome has the desired behavior.
