Setting authentication preferences

Users may authenticate with JSCAPE MFT Server using a variety of different authentication protocols. To view the current authentication method used click on the Authentication node for the desired domain.

Domain User Authentication is the most basic form of authentication, authenticating against local user accounts created for the domain using JSCAPE MFT Server Manager.

Database Authentication allows you to authenticate a user based on whether the user has credentials to connect to a database. When connecting to the supplied JDBC URL the username and password provided at time of login are used to login to the JDBC URL. If user authenticates successfully with the JDBC URL then user is considered a valid user of the JSCAPE MFT Server service.

JDBC URL - The JDBC URL used to connect to the database. Libraries for JDBC drivers must be placed in the libs/jdbc directory of your JSCAPE MFT Server installation, the JSCAPE MFT Server Service restarted and the JDBC driver class registered in Settings > JDBC Drivers in order for the database to be accessible to JSCAPE MFT Server.

Convert username before creation to - If enabled, the username supplied will be converted to specified case before passing username to specified User Template.

Database Query Authentication allows you to authenticate a user based on the results of a database query. If one or more records are returned from the query then the user is successfully authenticated.

SQL query - The query to perform to authenticate the user. There are two special variables that may be used when performing the database query %username% and %password% which refer the username and password passed in during the authentication process. Note, SQL queries and stored procedures may be used, however stored procedures which make use of output parameters may not be used. The variables %username% and %password% are treated as strings so must be enclosed in single quotes.

Hash password class - The Java class to use for hashing password before passing to SQL query. If no class is specified then password will be passed to SQL query in clear text.

Convert username before creation to - If enabled, the username supplied will be converted to specified case before passing username to specified User Template.

LDAP User Authentication allows you to authenticate a user based on whether the user has the credentials to connect to the LDAP or Active Directory service.

User DN - The users distinguished name for authenticating with the LDAP service. The variable %username% may be used which refers to the username passed in during the authentication process.

Allow anonymous binding - Sets whether user can bind anonymously to LDAP directory.

Create account if not found using template - This allows for accounts to be created automatically upon successful authentication. If selected, an account will be created automatically (if it does not exist already) using the specified User Template.

Convert username before creation to - If enabled, the username supplied will be converted to specified case before passing username to specified User Template.

Use failover server - If enabled and primary LDAP server is inaccessible then authentication will be attempted against failover server.

LDAP Query Authentication allows you to authenticate a user based on the results of a LDAP query and is a two step authentication process.

If one or more records are returned from the query then the user is successfully authenticated.

User DN - The users distinguished name for authenticating with the LDAP service.

Search user DN - The user distinguished name used for performing LDAP search query.

Filter - The filter to execute using the LDAP filter syntax. There are two special variables that may be used when performing the database query, %username% and %password% which refer the username and password supplied by the user during the authentication process.

Hash password class - The Java class to use for hashing password before passing to filter. If no class is specified then password will be passed to Filter in clear text.

Allow anonymous binding - Sets whether user can bind anonymously to LDAP directory.

Convert username before creation to - If enabled, the username supplied will be converted to specified case before passing username to specified User Template.

Use failover server - If enabled and primary LDAP server is inaccessible then authentication will be attempted against failover server.

When using LDAP Query Authentication you must define a filter that will be used to identify the record you are searching for. The syntax of LDAP filters are defined in RFC 2254. The table below provides a list of valid expressions and their meanings.

Symbol	Filter	Example	Example matches
=	Equality	(sn=Smith)	Surname of Smith only.
>	Greater than	(sn>Smith)	Any surname that alphabetically follows Smith.
>=	Greater than or equal to	(sn>=Smith)	Any surname that includes or alphabetically follows Smith.
<	Less than	(sn<Smith)	Any surname that alphabetically precedes Smith.
<=	Less than or equal to	(sn<=Smith)	Any surname that includes or alphabetically precedes Smith.
=*	Presence	(sn=*)	All surnames (all entries with the sn attribute).
=*	Substring	(sn=Smi*)	Any matching substring of Smith.
&	And	(& (sn=Smith) (cn=John) )	Surname of Smith and common name of John.
\|	Or	(\| (sn=Smith) (sn=Jones) )	Surname of Smith or Jones.
!	Not	(! (sn=Smith))	Surname not equal to Smith.

Using NTLM Authentication you may authenticate against an existing Windows domain.

Convert username before creation to - If enabled, the username supplied will be converted to specified case before passing username to specified User Template.

Using PAM Authentication you may authenticate against an existing UNIX PAM user repository. In order to use the PAM Authentication module you must install some native libraries that allow JSCAPE MFT Server to communicate with your PAM user repository.

Copy the native library to the Java Native Libary Path. See the Native Library Installation Location table for details. Note, Step 1 in the JPam instructions should be ignored as the jpam.jar file already exists in the libs directory of your JSCAPE MFT Server installation. Additionally, JPam instructions state you may optionally place native library in same directory as the jpam.jar file instead of the Java Native Library Path. This is incorrect. For JPam to work with JSCAPE MFT Server you must place native library in the Java Native Library Path and not in the libs directory of JSCAPE MFT Server.

Enable debug to file system_output.log - Sends debugging information to file system_output.log in installation directory.

Convert username before creation to - If enabled, the username supplied will be converted to specified case before passing username to specified User Template.

Using RADIUS authentication you may authenticate against an existing RADIUS server.

Max retransmit attempts - The maximum number of retransmission attempts when there is no response from the RADIUS server

Convert username before creation to - If enabled, the username supplied will be converted to specified case before passing username to specified User Template.

Using custom authentication you may define your own custom authentication class.

Convert username before creation to - If enabled, the username supplied will be converted to specified case before passing username to specified User Template.

Multiple authentication enables you to authenticate users using multiple authentication service types. One example use case is when you have some internal users who need to be authenticated using LDAP authentication and some external users who need to be authenticated using domain user authentication.

Note Multiple authentication is NOT 2-factor authentication or multi-factor authentication.

When you choose Multiple Authentication, you need to define a Primary and Secondary authentication type. The configuration details of each service type are the same as those described above.

When authenticating, the user is first authenticated against the Primary service. If the authentication is successful, the user is granted access. If the authentication fails, a second authentication attempt is made against the Secondary service. If the second authentication also fails, then the user is denied access; otherwise, access is granted.

Note For purposes of IP blocking/banning and raising of User Login event, this should only happen either after successful login OR after both Primary and Secondary authentication methods have been attempted.

The Database Query Authentication and LDAP Query Authentication services both support optional password hashing. Many databases and LDAP repositories store passwords in a hashed format. This is a security measure used in order to protect user credentials should a database or LDAP repository be compromised. JSCAPE MFT Server includes some built-in classes that may be used for hashing a password before it is sent for authentication against a database or LDAP repository. These classes are com.jscape.inet.mft.authentication.MD5Hasher and com.jscape.inet.mft.authentication.SHA1Hasher which offer MD5 and SHA1 hashes respectively. Note, the hashes provided by the MD5Hasher and SHA1Hasher classes are provided in lowercase format.

Some databases or LDAP repositories may store passwords in a salted hash format. In a salted hash format the password is combined with other data (the salt) prior to being hashed. Salted hash passwords are typically used in an effort to avoid brute-force password attacks should the database or LDAP repository be compromised. Password salting is generally application dependent, therefore should you need to use a salted password it is necessary to write your own password hasher using the JSCAPE MFT Server API. To implement your own password hashing provider you must perform the following:

1. Create a Java class which implements the com.jscape.inet.mft.authentication.Hasher class.

2. Overload the public String createHash(String login, String password) method, returning the hashed value.

3. Create a JAR file that contains the compiled version of your com.jscape.inet.mft.authentication.Hasher implementation. To compile your authentication class you will need to include the ftpserver.jar library in your classpath. The ftpserver.jar library may be found in the libs directory for JSCAPE MFT Server.

4. Place the JAR file created in step 3 into the libs directory of your JSCAPE MFT Server installation.

5. Shutdown any open instances of JSCAPE MFT Server Manager and restart the JSCAPE MFT Server Service.

6. In the Hash password class field of the Database Query Authentication or LDAP Query Authentication service enter the full classname, including package name of your hash provider.

SSO (Single-Sign-On) is a method by which users can login to one service (identity provider) and automatically be granted access to other services (service provider) without the need to login separately to these other services. An example of this would be logging into Google Apps and automatically be granted access to your JSCAPE MFT Server account without the need for a separate login. In the example screenshot below (Figure 171) Google Apps would serve as the identity provider and your JSCAPE MFT Server instance as the service provider. JSCAPE MFT Server provides support for web based SSO using SAML, OpenID and OpenID Connect compliant identity providers. Please consult the documentation of your identity provider for details on how to enable/configure SSO.

For example, if your hostname is 1.2.3.4 and your domain is mydomain this URL would look as follows:

If you have already authenticated with your identity provider then you will be automatically logged into JSCAPE MFT Server. If not, then you will be redirected to the Sign-in URL for your identity provider. After authenticating with your identity provider you will be automatically logged into JSCAPE MFT Server.

SSO applies only to web based sessions. Other protocols (FTP/S, SFTP, WebDAV, AFTP etc.) will authenticate users using the defined authentication service for the domain.

Note also that if SSO is used, users whose Prefer AFTP for JavaWS connections feature are enabled won't be able to connect.

The example provided below is for connecting with the Google Identity Platform. Sensitive information has been masked in the screenshot below.

Create user if not found using template - This allows for accounts to be created automatically upon successful authentication. If selected, an account will be created automatically (if it does not exist already) using the specified User Template. The Name and Login properties for the account created will automatically be set to the openid.identity attribute value.

Convert username before creation to - If enabled, the username supplied will be converted to specified case before passing username to specified User Template.

Allow non SSO logins - If enabled, user may login using either SSO or other authentication service
