If the server you are attempting to contact requires authentication, you will need to supply a username and password.  If you receive an "Bad Credentials" error from the server, check that you have entered the correct username and password and that you are authorized to access the files and directories you have chosen.

Your authentication credentials will determine your access rights to the files on the server.  If you receive "Permission Denied" or similar errors, it may indicate that the given username does not have access to a particular file or folder.

The username and password are always encrypted when communicating with the server, even if the "Encryption" checkbox is unchecked.


Usernames and passwords must be less than 32 characters, or the limit imposed by the server operating system, whichever is less.

Usernames and passwords should consist of only ASCII letters, numbers, and printable symbols.  The use of other characters, such as extended unicode characters, may work in some environments but is not assured and may compromise security.

Windows Domains

If the server is running on a Windows system with Active Directory or LDAP enabled, you may specify an authentication domain after your username by using the following syntax:


This should only be done for Windows servers which use explicit domains for authentication.
