Password and group file in datamover

Hi,

its not used for login since the data mover doesnt have a login shell

Normally you dont need the files

What they can be used for:

- ftp authentication
- NDMP authentication
- XML API authentication
- user mapping

The most common use is for NDMP auth - the other stuff normally gets done using other sources like AD, NIS, LDAP, ... these days

Hi,

So if we don't use these 4 service...(- ftp authentication- NDMP authentication - XML API authentication ) then we don't need NIS or LDAP also.. please correct me if i am wrong ..anyway what ever the file system we are exporting will be mounted by the client and once it is mounted it will be like local file system in that client... and if it is exported to multiple client.. then those client can be configured to NIS...why the data mover..? anyway the file access permission is determined by the user and group id.. and its stored in inode..

Thanks,

depends on the protocol

for just NFS without user mapping (to Windows users for multi-protocol access) you dont need any

some sort of host name resolution is nice - but you can use IP addresses for exports or use DNS
if I remember correctly only using netgroups for NFS export does require NIS

plus if you wont to use user quotas on the Celerra then its convinient to use names instead of UIDs and you would normally use NIS or LDAP for that

in terms of pure NFS access you're right - we get the numeric UID/GID value in the NFS reqeust and just compare the numeric values to the one's stored in the file system
we dont need to know user names or passwords there
