A ContextSource is responsible for configuring and creating DirContext instances. It is typically used from LdapTemplate to acquiring contexts for LDAP operations, but may be used standalone to perform LDAP authentication.

Method Summary

DirContext	getContext(String principal, String credentials) Gets a DirContext instance authenticated using the supplied principal and credentials.
DirContext	getReadOnlyContext() Gets a read-only DirContext.
DirContext	getReadWriteContext() Gets a read-write DirContext instance.

Method Detail

getReadOnlyContext

DirContext getReadOnlyContext()
                              throws NamingException

Gets a read-only DirContext. The returned DirContext must be possible to perform read-only operations on.

Returns:

A DirContext instance, never null.

Throws:

NamingException - if some error occurs creating an DirContext.

getReadWriteContext

DirContext getReadWriteContext()
                               throws NamingException

Gets a read-write DirContext instance.

Returns:

A DirContext instance, never null.

Throws:

NamingException - if some error occurs creating an DirContext.

getContext

DirContext getContext(String principal,
                      String credentials)
                      throws NamingException

Gets a DirContext instance authenticated using the supplied principal and credentials. Typically to be used for plain authentication purposes. Note that this method will never make use of native Java LDAP pooling, even though this instance is configured to do so. This is to force password changes in the target directory to take effect as soon as possible.

Parameters:

principal - The principal (typically a distinguished name of a user in the LDAP tree) to use for authentication.

credentials - The credentials to use for authentication.

Returns:

an authenticated DirContext instance, never null.

Throws:

NamingException
