Use Case: Create a User

This use case details tasks needed to create a user with limited access.

Create a Group

We recommend that you apply permissions to groups, not users. In this example, we will create a group for users with limited access.

Enter the following command to create a group for users who will be allowed create snapshots of volumes in Eucalyptus.
```
euare-groupcreate -g ebs-backup
```

Open an editor and enter the following JSON policy:

{
  "Statement": [
    {
      "Action": [
        "ec2:CreateSnapshot"
      ],
      "Effect": "Allow",
      "Resource": "*"
    }
  ]
}

Save and close the file.
Enter the following to add the new policy name allow-snapshot and the JSON policy file to the ebs-backup group:
```
euare-groupuploadpolicy -g ebs-backup -p allow-snapshot -f allow-snapshot.json
```

Create the user for the group with limited access.

Enter the following command to create the user sam in the group ebs-backup and generate a new key pair for the user:

euare-usercreate -u sam -g ebs-backup -k

Eucalyptus responds with the access key ID and the secret key, as in the following example:
