Possible krb5 regression in Fedora 32?

mount.cifs working on Fedora 31 instances (as well as CentOS 6 & CentOS 7 instances)

After upgrading an instance to Fedora 32, the mount now fails

Following troubleshooting, it was found that reverting from krb5--1.18.2-10 to krb5--1.17.1-5 resolves the issue

Is this a regression or could something be mis-configured on the KDC or SMB target?


The latest version works for me like this:

$ rpm -q krb5-libs 

$ sudo mount.cifs -o guest //host/share /mnt

Although don’t know much about the server:

$ nmap -sV -p 445 host | grep -e open
445/tcp open  netbios-ssn Samba smbd 3.X - 4.X

Try to compare old and new configs:


Also, I used to run Samba server in the past and old clients required to comment out this line:

includedir /etc/krb5.conf.d/
