Description of problem: pam_krb5 appears to never have been built for Fedora 32. I do not know if this is an oversight or deliberate decision. It is not present in the acecpted changes for F32, I am doing searches to find it if was oprhaned/retired and can find no such messages in the mailing lists. I use this quite a bit.
pam_krb5 was intentionally orphaned. I'm not sure why you can't find messages about that; it was done through normal Fedora process. My intent is for users to migrate to sssd. I wrote a guide for doing this at https://docs.pagure.org/SSSD.sssd/users/pam_krb5_migration.html If you need additional assistance, sssd folks can be reached at freenode/#sssd or sssd-users.org https://lists.fedorahosted.org/admin/lists/sssd-users.lists.fedorahosted.org/ Orphaning was done because sssd subsumes the functionality, and unlike pam_krb5 is actually maintained. While I can't stop you picking it up yourself again, you should know that the old pam_krb5 upstream we were using is no longer active, and pam_krb5 isn't shipped in EL either.
