public interface DirContextAuthenticationStrategy
A strategy to use when authenticating LDAP connections on creation. When
authenticating LDAP connections different strategies are needed depending on
the authentication mechanism used. Furthermore, depending on the mechanism
the work to be done needs to be applied at different stages of the
DirContext
creation process. A
DirContextAuthenticationStrategy contains the logic to perform a particular
type of authentication mechanism and will be called by its
ContextSource
at appropriate stages of the process.
Method Summary | |
---|---|
DirContext |
processContextAfterCreation(DirContext ctx,
String userDn,
String password)
This method is responsible for post-processing the DirContext instance after it has been created. |
void |
setupEnvironment(Hashtable env,
String userDn,
String password)
This method is responsible for preparing the environment to be used when creating the DirContext instance. |

void setupEnvironment(Hashtable env, String userDn, String password) throws NamingException
DirContext
instance. The base environment
(including URL, ContextFactory
etc. will already be set,
and this method is called just before the actual Context is to be
created.
env
- The Hashtable
to be sent to the
DirContext
instance on initialization. Pre-configured with
the basic settings; the implementation of this method is responsible for
manipulating the environment as appropriate for the particular
authentication mechanism.userDn
- the user DN to authenticate, as received from the
AuthenticationSource
of the ContextSource
.password
- the password to authenticate with, as received from the
AuthenticationSource
of the ContextSource
.
NamingException
- if anything goes wrong. This will cause the
DirContext
creation to be aborted and the exception to be
translated and rethrown.DirContext processContextAfterCreation(DirContext ctx, String userDn, String password) throws NamingException
DirContext
instance after it has been created. It will be
called immediately after the instance has been created. Some
authentication mechanisms, e.g. TLS, require particular stuff to happen
before the actual target Context is closed. This method provides the
possibility to replace or wrap the actual DirContext with a proxy so that
any calls on it may be intercepted.
ctx
- the freshly created DirContext
instance. The
actual implementation class (e.g. InitialLdapContext
)
depends on the ContextSource
implementation.userDn
- the user DN to authenticate, as received from the
AuthenticationSource
of the ContextSource
.password
- the password to authenticate with, as received from the
AuthenticationSource
of the ContextSource
.
NamingException
- if anything goes wrong. This will cause the
DirContext
creation to be aborted and the exception to be
translated and rethrown.
