A  I know its possible for standalone CIFS servers since it is used for some special configs where the Celerra is used as integrated storage where no domain controller is available and multi-protocol is needed for a few local accounts.  The setup isnt user-friendly and its up to engineering to allow it on a case-by-case basis. They might also require that its setup by an EMC technician.  Rainer
Hi,  Is it possible to map a Celerra windows local user to a unix user ? I tried but it seems to not work. The documentation does not mention this case. The local user has been created with windows mmc. This user is not meant to be used to log-in. The only goal is to grant access to a specific unix account by using a mapping rule and NT access policy. I know it would work with a regular AD account. Can't it work with a local account ?  I've done the following tests:  TESTMAPPING2 is CIFSSRV local user nobody_60001 is defined in local passwd file, with UID 60001. nsswitch.conf points files first.  1/ with the ntxmap rule "*:TESTMAPPING2:=:nobody_60001"  - add an ACL entry for CIFSSRV\TESTMAPPING2 on an existing object      -> no entry created in SECMAP (normaly it should) - make CIFSSRV\TESTMAPPING2 the ower of an existing object      -> no entry created in SECMAP (normaly it should)      -> the owner UID of the object is now 2155873260, but still no SECMAP entry - try to build the cred for my unix user (server_cifssupport server_2 -cred -uid 60001 -build)      -> Error 13160939531: server_2 : The NT credential for the user nobody_60001 uid 60001 cannot be built. Error 0xc0000064: NO_SUCH_USER.      2/ with the ntxmap rule ":TESTMAPPING2:=:nobody_60001" (removed the leading "*")  - try to build the cred for my unix user (server_cifssupport server_2 -cred -uid 60001 -build)      -> crash of the data mover  Any chance to make this work ? Thanks Eric
