LDAP authentication provider

Defining an LDAP authentication provider

In the application.properties file, these properties are expected for an LDAP authentication provider:

# Connection
blueriq.security.auth-providers.ldap01.type=ldap
blueriq.security.auth-providers.ldap01.connectionUrl=ldap://something.company.nl
blueriq.security.auth-providers.ldap01.userDn=cn=admin,ou=sysadmin,dc=mycompany,dc=com
blueriq.security.auth-providers.ldap01.password=<encryptedvalue_password>
blueriq.security.auth-providers.ldap01.useTls=true

# Connection protection (if 'useTls' is true)
blueriq.security.auth-providers.ldap01.tls.trustStoreUrl=file:///D:/location/to/your/certifactions.jks
blueriq.security.auth-providers.ldap01.tls.trustStorePassword=changeit
blueriq.security.auth-providers.ldap01.tls.trustStoreType=jks

# Search 
blueriq.security.auth-providers.ldap01.referralStrategy=follow
blueriq.security.auth-providers.ldap01.searchSubtree=true
# Search user
blueriq.security.auth-providers.ldap01.userSearchBaseDn=OU=users,DC=mycompany,DC=com
blueriq.security.auth-providers.ldap01.userSearchAttribute=sAMAccountName
# Search group
blueriq.security.auth-providers.ldap01.groupSearchBaseDn=OU=groups,DC=mycompany,DC=com
blueriq.security.auth-providers.ldap01.groupSearchFilterAttribute=cn
blueriq.security.auth-providers.ldap01.groupSearchFilterPattern=BQ_*, EVE_*,PRO - *,PRO -*
# role mapping
blueriq.security.auth-providers.ldap01.role-mapping.ldapGroup1=BlueriqRole1,BlueriqRole2
blueriq.security.auth-providers.ldap01.role-mapping.ldapGroup\ with\ spaces=BlueriqRole with spaces,BlueriqRoleC

The following fields are not required:

• trustStoreUrl, trustStorePassword and trustStoreType (unless useTls is set to true)

• groupSearchFilterPattern (unless groupSearchFilterAttribute is set)

• groupSearchFilterAttribute (unless groupSearchFilterPattern is set)

Setting TLS (Transport Layer Security)

useTls can be set to true, by doing so,  trustStoreUrl , trustStorePassword and trustStoreType need to be filled.

• trustStoreUrl: The location to the keystore where certificates are searched for when setting up the TLS connection to the LDAP server
• trustStorePassword: The password set for the keystore
• trustStoreType: what type of key store is used, like: 'jks' or 'pkcs12'
  
  

Make sure the keystore contains the certificates (certificate chain) needed to connect to the LDAP server.

Role mapping

The groups that are retrieved from the LDAP for a user need to be explicitly mapped to roles in Blueriq. The old behavior, in which all groups were mapped directly to roles, may lead to unwanted access for users that have certain groups  in LDAP that match Blueriq roles. To prevent this from happening, but also in the case that it does need to work this way, the role mapping needs to be defined explicitly. When no role mapping is defined, no roles will be mapped to the user, so when a flow requires a certain role, the user will not be able to access it.

The role mapping is defined by specifying the LDAP group and mapping it to a Blueriq role, separated with a comma if there are multiple, as shown in the property file above. Note that spaces in groups need to be escaped with a backslash (\). Roles can contain spaces.

Tooling tips

• Please refer to Property encryption when encrypting the LDAP password
• Use ADExplorer (Active Directory Explorer) to perform LDAP operations on an Active Directory server
• Use Keystore Explorer to see all the certificates in a keystore or to create your own keystore and fill it with certificates (instead of via command line tools like 'keytool')
