[management] add LDAP Referral property

[fbussolin]

I cannot use your version of ldap feature/plugin in my shop because the referral property is not set. Due to this the following exception is throw:

• Unprocessed Continuation Reference(s); nested exception is javax.naming.PartialResultException: Unprocessed Continuation Reference(s); remaining name ''

Expected Behavior

LDAP Authentication OK

Current Behavior

Exception:

• Unprocessed Continuation Reference(s); nested exception is javax.naming.PartialResultException: Unprocessed Continuation Reference(s); remaining name ''

Possible Solution

In io.gravitee.rest.api.idp.ldap.authentication.LdapAuthenticationProvider create a property to allow the enabling and setup of referral in DefaultSpringSecurityContextSource creation.

For your evaluation, something like that: if(environment.getProperty("context.referral.enabled")) then contextSource.setReferral(environment.getProperty("context.referral.value"));

Steps to Reproduce (for bugs)

1. Set the following: security: providers:

   • type: ldap context: username: "" password: "" url: "ldap://address:389/DC=v1,DC=v2,DC=v3" base: "DC=v1,DC=v2,DC=v3" authentication: user: base: "OU=Users,OU=Group1,OU=Group2" filter: "mail={0}" lookup: user: base: "OU=Users,OU=Group1,OU=Group2" filter: "(&(objectClass=user)(objectClass=person)(|(cn={0})(mail={0})))"

2. Try to use LDAP feature/plugin from management-ui

Context

I have a custom version of your plugin setting the referral property to "follow".

Your Environment

• Version used: 3.7.0
• Browser Name and version: Google Chrome Version 89.0.4389.114 (Official Build) (64-bit)
• Operating System and version: OpenShift 3.11
