Working with user/group mappings in the ECS Portal
You can use the
User/Group Mapping tab on the
File page available from
Manage > File to view the existing mappings between ECS object users/groups and Unix users, to create new user/group mappings, and to edit mappings.
The
User/Group Mapping tab has a
Namespace field that allows you to select the namespace for which you want to see the configured user/group mappings.
ECS stores the owner and group for the bucket, and the owner and group for files and directories within the bucket, as ECS object username and custom group names, respectively. The names must be mapped to Unix IDs in order that NFS users can be given access with the appropriate privileges.
The mapping enables ECS to treat an ECS object user and an NFS user as the same user but with two sets of credentials, one to access ECS using NFS, and one to access the ECS using the object protocols. Because the accounts are mapped, files written by an NFS user will be accessible as objects by the mapped object user and objects written by the object users will be accessible as files by the NFS user.
The permissions associated with the file or object will be based on a mapping between POSIX and object protocol ACL privileges. For more information, see
Multi-protocol access permissions.
