LDAP Connection

Overview

Fusion Metadata Registry can use LDAP as the authorization mechanism

Setting up an LDAP connection

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

Troubleshooting

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

<logger name="org.springframework.security" level="DEBUG" additivity="false">
    <appender-ref ref="STDOUT" />
</logger>
<logger name="org.springframework.ldap" level="DEBUG" additivity="false">
    <appender-ref ref="STDOUT" />
</logger>
