File provider

A file provider enables you to supply an authoritative third-party source of user and group information to a PowerScale cluster. A third-party source is useful in UNIX and Linux environments that synchronize /etc/passwd, /etc/group, and etc/netgroup files across multiple servers.

Standard BSD /etc/spwd.db and /etc/group database files serve as the file provider backing store on a cluster. You generate the spwd.db file by running the pwd_mkdb command in the OneFS command-line interface (CLI). You can script updates to the database files.

On a PowerScale cluster, a file provider hashes passwords with libcrypt. For the best security, it is recommended that you use the Modular Crypt Format in the source /etc/passwd file to determine the hashing algorithm. OneFS supports the following algorithms for the Modular Crypt Format:

  • MD5
  • NT-Hash
  • SHA-256
  • SHA-512

For information about other available password formats, run the man 3 crypt command in the CLI to view the crypt man pages.

NOTE The built-in System file provider includes services to list, manage, and authenticate against system accounts such as root, admin, and nobody. It is recommended that you do not modify the System file provider.
