As root, this works fine: $ mount -t cifs -o credentials=/etc/creds,vers=1.0,multiuser,sec=ntlmss //example.host.org/pnl /data/pnl/ $ ls /data/pnl/ (all files are listed) But as unprivileged user abc, this does not work: $ cifscreds add -u abc example.host.org $ ls /data/pnl/ ls: cannot access '/data/pnl/': Permission denied === In /var/log/messages, I get the unhelpful error log: CIFS: Status code returned 0xc000006d NT_STATUS_LOGON_FAILURE CIFS: VFS: \\erisonefs.partners.org Send error in SessSetup = -13 === Observations contradictory to the above: (1) The above multiuser mount worked fine in CentOS 7. The problem is happening after upgrade to CentOS 9 Stream. (2) Direct mount as abc works fine: mount -t cifs -o user=abc,vers=1.0 //example.host.org/pnl /data/pnl/ ls /data/pnl/ (all files are listed) === Can I get some help? Thanks, Tashrif
