Package: cifs-utils Version: 2:6.6-5 Severity: normal Hello, I am able to mount with the following command with root using the following command: mount -t cifs //smb.physics.wisc.edu/smb /smb -osec=krb5,multiuser,username=smbad...@physics.wisc.edu --verbose
root can also access files as expected However, when cifs-utils 6.6-5 is installed, a different user cannot access as expected: ls /smb ls: cannot access '/smb': Permission denied But when cifs-utils 6.4-1 is installed (from jessie) the different user can access as expect. AFAIK there are no other differences besides the cifs-utils version. The first difference in syslog is "kernel: [223018.425633] CIFS VFS: Send error in SessSetup = -126". I'll paste the working and non-working logs below. The "different user" mentioned above has UID 1494 which appears in the logs. Thanks for your time! C.
