We have noticed that a CIFS/SMB mount to a CIFS share on our netapp filer does not work. NTLM mounts work, but if you use KRB5 security it does not work.
If you try to make a mount the response is : "Input/output error" There is already a bugreport on this : https://bugzilla.samba.org/show_bug.cgi?id=6682 Has anyone more information about this so we can work around it ? It has to do with "extended security negotiation". The mount command we use is : mount.cifs //server.domain.net/homedir -o sec=krb5i Note : smbclient with krb5 support works. I have tested this. A cifs mount to one of our windows server works as expected. (It always has) After increasing debug info you can see that a working mount to a windows server shows the following : fs/cifs/cifssmb.c: Dialect: 2 fs/cifs/asn1.c: OID len = 7 oid = 0x1 0x2 0x348 0xbb92 fs/cifs/asn1.c: OID len = 7 oid = 0x1 0x2 0x348 0x1bb92 fs/cifs/asn1.c: OID len = 8 oid = 0x1 0x2 0x348 0x1bb92 fs/cifs/asn1.c: OID len = 10 oid = 0x1 0x3 0x6 0x1 fs/cifs/cifssmb.c: Must sign - secFlags 0x1009 fs/cifs/cifssmb.c: negprot rc 0 mount that fails (NetApp server): fs/cifs/cifssmb.c: Dialect: 2 fs/cifs/cifssmb.c: negprot rc -5 Greetings ...
