type UpdateUserInput struct {

	// A system-assigned unique identifier for a Transfer Family server instance that
	// the user is assigned to.
	//
	// This member is required.
	ServerId *string

	// 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.
	//
	// This member is required.
	UserName *string

	// The landing directory (folder) for a user when they log in to the server using
	// the client. A HomeDirectory example is /bucket_name/home/mydirectory . The
	// HomeDirectory parameter is only used if HomeDirectoryType is set to PATH .
	HomeDirectory *string

	// Logical directory mappings that specify what Amazon S3 or Amazon EFS paths and
	// keys should be visible to your user and how you want to make them visible. You
	// must specify the Entry and Target pair, where Entry shows how the path is made
	// visible and Target is the actual Amazon S3 or Amazon EFS path. If you only
	// specify a target, it is displayed as is. You also must ensure that your Identity
	// and Access Management (IAM) role provides access to paths in Target . This value
	// can be set only when HomeDirectoryType is set to LOGICAL. The following is an
	// Entry and Target pair example. [ { "Entry": "/directory1", "Target":
	// "/bucket_name/home/mydirectory" } ] In most cases, you can use this value
	// instead of the session policy to lock down your user to the designated home
	// directory (" chroot "). To do this, you can set Entry to '/' and set Target to
	// the HomeDirectory parameter value. The following is an Entry and Target pair
	// example for chroot . [ { "Entry": "/", "Target":
	// "/bucket_name/home/mydirectory" } ]
	HomeDirectoryMappings []types.HomeDirectoryMapEntry

	// The type of landing directory (folder) that you want your users' home directory
	// to be when they log in to the server. If you set it to PATH , the user will see
	// the absolute Amazon S3 bucket or Amazon EFS path as is in their file transfer
	// protocol clients. If you set it to LOGICAL , you need to provide mappings in the
	// HomeDirectoryMappings for how you want to make Amazon S3 or Amazon EFS paths
	// visible to your users. If HomeDirectoryType is LOGICAL , you must provide
	// mappings, using the HomeDirectoryMappings parameter. If, on the other hand,
	// HomeDirectoryType is PATH , you provide an absolute path using the HomeDirectory
	// parameter. You cannot have both HomeDirectory and HomeDirectoryMappings in your
	// template.
	HomeDirectoryType types.HomeDirectoryType

	// A session policy for your user so that you can use the same Identity and Access
	// Management (IAM) role across multiple users. This policy scopes down a user's
	// access to portions of their Amazon S3 bucket. Variables that you can use inside
	// this policy include ${Transfer:UserName} , ${Transfer:HomeDirectory} , and
	// ${Transfer:HomeBucket} . This policy applies only when the domain of ServerId
	// is Amazon S3. Amazon EFS does not use session policies. For session policies,
	// Transfer Family stores the policy as a JSON blob, instead of the Amazon Resource
	// Name (ARN) of the policy. You save the policy as a JSON blob and pass it in the
	// Policy argument. For an example of a session policy, see Creating a session
	// policy (https://docs.aws.amazon.com/transfer/latest/userguide/session-policy) .
	// For more information, see AssumeRole (https://docs.aws.amazon.com/STS/latest/APIReference/API_AssumeRole.html)
	// in the Amazon Web Services Security Token Service API Reference.
	Policy *string

	// Specifies the full POSIX identity, including user ID ( Uid ), group ID ( Gid ),
	// and any secondary groups IDs ( SecondaryGids ), that controls your users' access
	// to your Amazon Elastic File Systems (Amazon EFS). The POSIX permissions that are
	// set on files and directories in your file system determines the level of access
	// your users get when transferring files into and out of your Amazon EFS file
	// systems.
	PosixProfile *types.PosixProfile

	// The Amazon Resource Name (ARN) of the Identity and Access Management (IAM) role
	// that controls your users' access to your Amazon S3 bucket or Amazon EFS file
	// system. The policies attached to this role determine the level of access that
	// you want to provide your users when transferring files into and out of your
	// Amazon S3 bucket or Amazon EFS file system. The IAM role should also contain a
	// trust relationship that allows the server to access your resources when
	// servicing your users' transfer requests.
