updateUser method

Future<UpdateUserResponse> updateUser({
  1. required String serverId,
  2. required String userName,
  3. String? homeDirectory,
  4. List<HomeDirectoryMapEntry>? homeDirectoryMappings,
  5. HomeDirectoryType? homeDirectoryType,
  6. String? policy,
  7. String? role,
})

Assigns new properties to a user. Parameters you pass modify any or all of the following: the home directory, role, and policy for the UserName and ServerId you specify.

The response returns the ServerId and the UserName for the updated user.

May throw ServiceUnavailableException. May throw InternalServiceError. May throw InvalidRequestException. May throw ResourceNotFoundException. May throw ThrottlingException.

Parameter serverId : A system-assigned unique identifier for a server instance that the user account is assigned to.

Parameter userName : A unique string that identifies a user and is associated with a server as specified by the ServerId. This user name must be a minimum of 3 and a maximum of 100 characters long. The following are valid characters: a-z, A-Z, 0-9, underscore '_', hyphen '-', period '.', and at sign '@'. The user name can't start with a hyphen, period, or at sign.

Parameter homeDirectory : Specifies the landing directory (folder) for a user when they log in to the server using their file transfer protocol client.

An example is your-Amazon-S3-bucket-name>/home/username.

Parameter homeDirectoryMappings : Logical directory mappings that specify what Amazon S3 paths and keys should be visible to your user and how you want to make them visible. You will need to specify the "Entry" and "Target" pair, where Entry shows how the path is made visible and Target is the actual Amazon S3 path. If you only specify a target, it will be displayed as is. You will need to also make sure that your IAM role provides access to paths in Target. The following is an example.

' "/bucket2/documentation", { "Entry": "your-personal-report.pdf", "Target": "/bucket3/customized-reports/${transfer:UserName}.pdf" } '

In most cases, you can use this value instead of the scope-down policy to lock your user down to the designated home directory ("chroot"). To do this, you can set Entry to '/' and set Target to the HomeDirectory parameter value.

Parameter homeDirectoryType : The type of landing directory (folder) you want your users' home directory to be when they log into the server. If you set it to PATH, the user will see the absolute Amazon S3 bucket paths as is in their file transfer protocol clients. If you set it LOGICAL, you will need to provide mappings in the HomeDirectoryMappings for how you want to make Amazon S3 paths visible to your users.

Parameter policy : Allows you to supply a scope-down policy for your user so you can use the same IAM role across multiple users. The policy scopes down user access to portions of your Amazon S3 bucket. Variables you can use inside this policy include ${Transfer:UserName}, ${Transfer:HomeDirectory}, and ${Transfer:HomeBucket}.

For an example of a scope-down policy, see Creating a scope-down policy.

For more information, see AssumeRole in the AWS Security Token Service API Reference.

Parameter role : The IAM role that controls your users' access to your Amazon S3 bucket. The policies attached to this role will determine the level of access you want to provide your users when transferring files into and out of your Amazon S3 bucket or buckets. The IAM role should also contain a trust relationship that allows the server to access your resources when servicing your users' transfer requests.
