As a security administrator, you can create S Series Node user accounts. When you create a user account, you specify a username for the account. The username uniquely identifies that account on the S Series Node.
Usernames:
- Must be 3 through 128 characters long
- Can contain only valid UTF-8 characters
- Cannot contain uppercase letters
- Cannot contain an opening angle bracket (<) or closing angle bracket (>)
- Cannot start with an opening square bracket ([) or closing square bracket (])
- Cannot contain white space
- Must be unique for the current S Series Node
Additionally, the following strings are reserved and cannot be used as usernames:
- allusers
- authenticatedusers
- internal
- logdelivery
- http://acs.amazonaws.com/groups/global/allusers
- http://acs.amazonaws.com/groups/global/authenticatedusers
- http://acs.amazonaws.com/groups/s3/logdelivery
You can reuse usernames that are not currently in use. For example, if you delete the account for a user, you can create a new account for that user with the same username as the deleted account had.
