javax.naming.AuthenticationNotSupportedException: [LDAP: error code 8 - How to check customer environment before setting env values for JNDI call ?
shivaraj
While connecting to AD via JNDI, I am getting a error like:
javax.naming.AuthenticationNotSupportedException: [LDAP: error code 8
- 00002028: LdapErr: DSID-0C0901FC, comment: The server requires binds
to turn on integrity checking if SSL\TLS are not already active on the
connection, data 0, v1771]
From googling what I came across is, this will be thrown when a
particular flavor of authentication requested is not supported. It may
be specified using specific authentication schemes such those
identified using SASL.
And I also got a hint that, the solution would be to use
env.put("javax.security.sasl.qop","auth-int");
But my query is, I will be running the same LDAP connectivity tool (my
tool) with many customers. So how should I test if they are using
1. Normal LDAP port: 389? or they are using SSL/TSL connection with
different port number ?
2. How to check what security authentication to use ? i.e setting
Context.SECURITY_AUTHENTICATION to "none", "simple", sasl_mech, ?
Is there a sample code which I can run and fetch customer setup
details (about if SSL is enabled or not etc ) before I set my LDAP env
attributes?
