On the page page Security -> Role Mappings you will need to define what a group in your LDAP directory will have permission to perform. The permissions are:
 
−
* Administrator privileges - user may perform all tasks
 
−
* Agency privileges - the ability to provide structural metadata for a particular agency
 
−
* Data Provider privileges - the ability to provide data for a particular Data Provider
 
−
* Data Consumer privileges - the ability to consume data for a particular Data Consumer
 
−
 
 
−
As single user can be given as many privileges as necessary.

−
To give an example of how a mapping should be used, suppose users exist in your LDAP system which are members of the group "STRUC_MAINTAINERS".  You want all of the users in this group to be able to create and modify SDMX, BIS and ECB structural metadata.  On the FMR Role Mappings page, create a group with the name "STRUC_MAINTAINERS" and assign this group to Agencies SDMX, BIS and ECB.  All users now should find that they have permission to modify structural metadata for those agencies.

If you are having issues connecting to LDAP, please look at the logs of FMR.  To aid in this, you may wish to increase the logging level of the LDAP connectors.  Please add the following loggers to the file: '''logback.xml''' to set the logging to DEBUG for Spring classes

A Docker OpenLdap instance is available and for more information can be found at: https://github.com/rroemhild/docker-test-openldap

The command to create and run the docker instance is:

Within this docker instance there are:

−
- 2 groups in the OpenLDAP system: "admin_staff" and "ship_crew"
 
−
- 2 users in "admin_staff": "professor" and "hermes"
 
−
- 3 users in "ship_crew": "fry", "bender" and "leela"

For convenience everyone's password is the same as their UID. These credentials will be used to login to the Registry.

−
* Note how this user can only edit SDMX structures
 
−
* Edit the Role Mapping so that "ship_crew" is now an administrator
 
−
* In the other browser, log off and the log on as "fry".
 
−
* Note this user is now an administrator

Overview

Fusion Registry can use LDAP as the authorization mechanism

Defining an LDAP connection

Specifying the Connection Details

On the page page Security -> Authentication Service ensure the drop-down states "LDAP". The following fields are presented.

Item Description
Protocol and hostname Mandatory Either select ldap or ldaps (LDAP over SSL) in the left-side drop-down. In the input field, enter the server and if necessary port number. E.g. localhost:10389
Base DN The Base Distinguished Name identifies the entry in the directory from which searches initiated by LDAP clients occur. E.g dc=metdatatechnology,dc=com
Manager DN The manager DN used for querying the directory server and so this user must have privileges to search the directory. E.g. cn=admin,dc=metdatatechnology,dc=com
Manager Password The password for the manager account
User Search Base The starting point the LDAP server uses when searching for users authentication within your directory. This works in tandem with the base DN. E.g A value of "ou=people" would search under "ou=people" under the Base DN "dc=metdatatechnology,dc=com"
User Search Filter Used to identify the users under the User Search Base by a particular criteria. This is often likely to be: uid={0}
Group Search Base The starting point the LDAP server uses when searching for groups within your directory. This works in tandem with the base DN. E.g A value of "ou=people" would search for groups under "ou=people" under the Base DN "dc=metdatatechnology,dc=com"
Group Search Filter Used to identify the groups under the Group Search Base by a particular criteria. E.g. member={0}
Role Prefix An optional prefix which will be prepended to Granted Authority values loaded from the directory.
UserID Attribute Mandatory This is used to determine what value a user should be displayed as. It is likely this value will be uid

Once the LDAP server has been set up correctly you should find that attempts to logon as a user from your LDAP directory may be refused permission due to lack of permissions.

The next step is to set up Fusion Security Manager.
