Constructor Detail

LDAPMapper

public LDAPMapper(LDAPConfiguration conf)

Creates a new mapper and establish the connection using given LDAPConfiguration.
IMPORTANT: Don't forget to call disconnect() when finished with this mapper.
If an error occurs during connection, the LDAPException describing the error is accessible using getLastException()

Parameters:

conf - the LDAPConfiguration to use for this mapper

Method Detail

getUserLDAPEntry

public com.unboundid.ldap.sdk.SearchResultEntry getUserLDAPEntry(java.lang.String login,
                                                        java.lang.String[] attrs)

Return the first matching LDAP Entry for the given login.
Uses : - LDAPConfiguration.getSuffix() (search baseDN) - LDAPConfiguration.getUserFilter() (search filter)

Parameters:

login - the login of the member of which to retrieve SearchResultEntry.

attrs - attributes you want returned in the result.

Returns:

the first SearchResultEntry retrieved from LDAP, or null if member is not found or if an error occured (in which case getLastException(). A warning message is logged if more than one entries have been found (in which case you should refine your user search filter).

Since:

jcms-5.7.0

getUserLDAPEntryFromDN

public com.unboundid.ldap.sdk.SearchResultEntry getUserLDAPEntryFromDN(java.lang.String fullDN,
                                                              java.lang.String[] attrs)

Retrieve a User entry from its exact DN.

This method differs from the LDAPConnection.getEntry(String, String[]) because it will apply the user filter configured in JCMS (LDAPConfiguration.getUserFilter()

Parameters:

fullDN - the DN of the User entry to retrieve

attrs - attributes you want returned in the result entry.

Returns:

the SearchResultEntry retrieved from LDAP, null if LDAP entry could not be found. Also returns null if several entries were found, this prevents invalid behavior if bad DN is specified (a warning is issued in the logs)

Since:

jcms-7.0

getUsersLDAPEntries

Retrieve all user SearchResultEntry matching current configuration.

This implementation does not scale to thousands users/groups and may consume lot of memory as all LDAP user entry are retrieved at once from the LDAP.

Parameters:

sortKeys - the LDAP attribute names to use for sorting of LDAP entry, eg "cn"

attrs - attributes you want returned in the result entry.

Returns:

a list of all SearchResultEntry retrieved from LDAP, never return null

Since:

jcms-9.0.1

Return the groups LDAP Entry for the given dn (dn of a user or a sub-group).
Uses : - LDAPConfiguration.getGroupSuffix() (search baseDN) - LDAPConfiguration.getGroupFilter() (search filter)

Parameters:

dn - the dn of the user of which to retrieve groups' SearchResultEntry.

attrs - attributes you want returned in the result.

Returns:

a list of SearchResultEntry retrieved from LDAP, or null if no group is found or if an error occured (in which case getLastException().

Retrieve a Group entry from its exact DN.

This method differs from the LDAPConnection.getEntry(String, String[]) because it will apply the group filter configured in JCMS (LDAPConfiguration.getGroupFilter()

Parameters:

fullDN - the DN of the Group entry to retrieve

attrs - attributes you want returned in the result entry.

Returns:

the SearchResultEntry retrieved from LDAP, null if LDAP entry could not be found. Also returns null if several entries were found, this prevents invalid behavior if bad DN is specified (a warning is issued in the logs)
