Class UserAccount

java.lang.Object

org.mockftpserver.fake.UserAccount

public class UserAccount
extends Object

Represents a single user account on the server, including the username, password, home directory, list of groups to which this user belongs, and default permissions applied to newly-created files and directories.

The username and homeDirectory property must be non-null and non-empty. The homeDirectory property must also match the name of an existing directory within the file system configured for the FakeFtpServer.

The group name applied to newly created files/directories is determined by the groups property. If null or empty, then the default group name ("users") is used. Otherwise, the first value in the groups List is used. The groups property defaults to an empty List.

The default value for defaultPermissionsForNewFile is read and write permissions for all (user/group/world). The default value for defaultPermissionsForNewDirectory is read, write and execute permissions for all (user/group/world).

The isValidPassword() method returns true if the specified password matches the password value configured for this user account. This implementation uses the isEquals() method to compare passwords.

If you want to provide a custom comparison, for instance using encrypted passwords, you can subclass this class and override the comparePassword() method to provide your own custom implementation.

If the passwordCheckedDuringValidation property is set to false, then the password value is ignored, and the isValidPassword() method just returns true.

The accountRequiredForLogin property defaults to false. If it is set to true, then it is expected that the login for this account will require an ACCOUNT (ACCT) command after the PASSWORD (PASS) command is completed.

getPrimaryGroup

public String getPrimaryGroup()

Return the name of the primary group to which this user belongs. If this account has no associated groups set, then this method returns the DEFAULT_GROUP. Otherwise, this method returns the first group name in the groups list.

Parameters:

password - - the password to compare against the configured value

Returns:

true if the password is correct and valid

Throws:

AssertFailedException - - if the username property is null

isValid

public boolean isValid()

Returns:

true if this UserAccount object is valid; i.e. if the homeDirectory is non-null and non-empty.

toString

public String toString()

Overrides:

toString in class Object

Returns:

the String representation of this object

canRead

public boolean canRead(FileSystemEntry entry)

Return true if this user has read access to the file/directory represented by the specified FileSystemEntry object.

Parameters:

Returns:

true if the passwords match
