getNewUserDirectorySpecificAttributes

protected void getNewUserDirectorySpecificAttributes(User user,

Populates attributes object with directory-specific attributes.

Overrider of this method can take advantage of the default group attributes mapping logic in {#getNewUserAttributes(User)}.

Note that the attribute values supplied here will be used raw. This entails that overrider is responsible for supplying values in a format supported by the directory. In some directory implementations, for example, a blank string ("") is considered illegal. Overrider thus would have to make sure the method does not generate a value as such.

Parameters:

user - (potential) source of information that needs to be added.

attributes - attributes to add directory-specific information to.

Description copied from interface: LDAPDirectory

Finds a directory entity (principal, group or role) by their distinguished name.

The object class of an entity is used to determine the entity type.

If an object represents both a group and role, then the object is mapped to a group.

Specified by:

findEntityByDN in interface LDAPDirectory

Parameters:

dn - standardised distinguished name.

entityClass - class of the entity to find (either LDAPUserWithAttributes or LDAPGroupWithAttributes).

Returns:

directory entity corresponding to DN.

Throws:

UserNotFoundException - if a user does not exist at the specified DN or the DN does not exist in the directory. This will also be thrown if the entity DOES exist but does not match the base DN or object filter for the entity type.

GroupNotFoundException - if a user does not exist at the specified DN or the DN does not exist in the directory. This will also be thrown if the entity DOES exist but does not match the base DN or object filter for the entity type.

OperationFailedException - if underlying directory implementation failed to execute the operation.

getNewGroupDirectorySpecificAttributes

protected void getNewGroupDirectorySpecificAttributes(Group group,

Parameters:

group - (potential) source of information that needs to be added.

attributes - attributes to add directory-specific information to.

testConnection

public void testConnection()
                    throws OperationFailedException

Description copied from interface: RemoteDirectory

Test if a connection to the directory server can be established. When executed for a directory already persisted in the database (ie with a non-null id) the connection will be taken using the same semantics as during regular directory operations, which means that the connection may be sourced from a connection pool and be subject to additional validation if applicable. This gives a good indicator as to the RemoteDirectory's status but can be problematic when used to verify correctness during a directory update. If absolute certainty about the RemoteDirectory's status is not needed or the RemoteDirectory's lifecycle will be limited strictly to the connection test, CrowdDirectoryService.testConnection(Directory) should be used instead.

Specified by:

testConnection in interface RemoteDirectory

Throws:

OperationFailedException - underlying directory implementation failed to execute the operation.
