Table: Naming requirements for adding new users
Letter or an underscore (_)
Must begin with an alphabetic character and the rest of the string should be from the following POSIX portable character set: ([A-Za-z_][A-Za-z0-9_-.]*[A-Za-z0-9_-.$]).
Can be up to 31 characters. If user names are greater than 31 characters, you will receive the error, "Invalid user name."
FileStore CLI commands are case-insensitive (for example, the user command is the same as the USER command). However, user-provided variables are case-sensitive (for example, the username Master1 is not the same as the username MASTER1).
Hyphens (-) and underscores (_) are allowed.
Valid user names include:
See Creating Master, System Administrator, and Storage Administrator users.
