Hi I have a s3 fileserver joined to a s4 DC Here is smb.conf on the fileserver: [global] workgroup = HH3 realm = HH3.SITE security = ADS kerberos method = system keytab winbind enum users = Yes winbind enum groups = Yes idmap config *:backend = tdb idmap config *:range = 3000-4000 idmap config HH3:backend = ad idmap config HH3:range = 20000-40000000 idmap config HH3:schema_mode = rfc2307 winbind nss info = rfc2307 winbind expand groups = 2 winbind nested groups = yes winbind use default domain = Yes [users] path = /home/users read only = No getent passwd works fine and shows AD users. But cifs mount fails: sudo mount -t cifs //oliva/users --verbose /mnt -osec=krb5 mount.cifs kernel mount options: ip=127.0.0.1,unc=\\oliva \users,sec=krb5,user=root,pass=******** mount error(13): Permission denied Refer to the mount.cifs(8) manual page (e.g. man mount.cifs) the log gives: May 26 12:35:05 oliva cifs.upcall: key description: cifs.spnego;0;0;39010000;ver=0x2;host=oliva;ip4=127.0.0.1;sec=krb5;uid=0x0;creduid=0x0;user=root;pid=0x6f3 May 26 12:35:05 oliva cifs.upcall: ver=2 May 26 12:35:05 oliva cifs.upcall: host=oliva May 26 12:35:05 oliva cifs.upcall: ip=127.0.0.1 May 26 12:35:05 oliva cifs.upcall: sec=1 May 26 12:35:05 oliva cifs.upcall: uid=0 May 26 12:35:05 oliva cifs.upcall: creduid=0 May 26 12:35:05 oliva cifs.upcall: user=root May 26 12:35:05 oliva cifs.upcall: pid=1779 May 26 12:35:05 oliva cifs.upcall: find_krb5_cc: considering /tmp/krb5cc_0 May 26 12:35:05 oliva cifs.upcall: find_krb5_cc: FILE:/tmp/krb5cc_0 is valid ccache May 26 12:35:05 oliva cifs.upcall: handle_krb5_mech: getting service ticket for oliva May 26 12:35:05 oliva cifs.upcall: handle_krb5_mech: obtained service ticket May 26 12:35:05 oliva kernel: [ 612.342045] Status code returned 0xc000006d NT_STATUS_LOGON_FAILURE May 26 12:35:05 oliva kernel: [ 612.342109] CIFS VFS: Send error in SessSetup = -13 May 26 12:35:05 oliva kernel: [ 612.343323] CIFS VFS: cifs_mount failed w/return code = -13 smbd fails with this: Maximum core file size limits now 16777216(soft) -1(hard) smbd version 3.6.9 started.
