Prior to this change, ApacheDSContainer created a LdifFileLoader
without a ClassLoader. This limited its ability to load LDIF files
and causes a problem with an executable war in Spring Boot. See [1]
for details.
ApacheDSContainer now initialises LdifFileLoader with a ClassLoader.
This allows it to locate LDIF files packaged in WEB-INF/classes in
the case of an executable war file. The executable jar case was not
affected by this problem as, in that case, the LDIF file is pacakaged
in the root of the jar and is accessible via getSystemResourceAsStream

This refers to groups that have member: <another group DN> as an attribute
- Add in a utility method in the SpringSecurityLdapTemplate to retrieve multiple attributes and their values from an LDAP record
- Make the DefaultLdapAuthoritiesPopulator more extensible
- Add an LdapAuthority object that holds the DN in addition to other group attributes
- Add a NestedLdapAuthoritiesPopulator to search statically nested groups
A number of projects had duplicate dependencies on their classpaths
as a result of the same classes being available in more than one
artifact, each with different Maven coordinates. Typically this only
affected the tests, but meant that the actual classes that were
loaded was somewhat unpredictable and had the potential to vary
between an IDE and the command line depending on the order in which
the aritfacts appeared on the classpath. This commit adds a number of
exclusions to remove such duplicates.
In addition to the new exclusions, notable other changes are:
- Spring Data JPA has been updated to 1.4.1. This brings its
transitive dependency upon spring-data-commons into line with
Spring LDAP's and prevents both spring-data-commons-core and
spring-data-commons from being on the classpath
- All Servlet API dependencies have been updated to use the official
artifact with all transitive dependencies on unofficial servlet API
artifacts being excluded.
- In places, groovy has been replaced with groovy-all. This removes
some duplicates caused by groovy's transitive dependencies.
- JUnit has been updated to 4.11 which brings its transitive Hamcrest
dependency into line with other components.
There appears to be a bug in Gradle which means that some exclusions
applied to an artifact do not work reliably. To work around this
problem it has been necessary to apply some exclusions at the
configuration level

Previously communication errors with LDAP were only logged at debug level.
Communication errors (along with other non-authenticated related NamingExceptions)
are now logged as error messages. We created an InternalAuthetnicationServiceException
to represent errors that should be logged as errors to distinguish between internal
and external authentication failures. For example, we do not want an OpenID Provider
being able to report errors that cause our logs to fill up. However, an LDAP system is
internal and should be trusted so logging at an error level makes sense.
Previously there was no way to extract the original exception or to easily
obtain details about the failure if Spring Security was not able to translate
the exception into a Spring Security AuthenticationException.
Now the caused by is an ActiveDirectoryAuthenticationException which contains
the original Active Directory error code.
