Method Detail

compare

public boolean compare(String dn,
              String attributeName,
              Object value)

Performs an LDAP compare operation of the value of an attribute for a particular directory entry.

Parameters:

dn - the entry who's attribute is to be used

attributeName - the attribute who's value we want to compare

value - the value to be checked against the directory value

Returns:

true if the supplied value matches that in the directory

retrieveEntry

public DirContextOperations retrieveEntry(String dn,
                                 String[] attributesToRetrieve)

Composes an object from the attributes of the given DN.

Parameters:

dn - the directory entry which will be read

attributesToRetrieve - the named attributes which will be retrieved from the directory entry.

Returns:

the object created by the mapper

searchForSingleAttributeValues

public Set<String> searchForSingleAttributeValues(String base,
                                         String filter,
                                         Object[] params,
                                         String attributeName)

Performs a search using the supplied filter and returns the union of the values of the named attribute found in all entries matched by the search. Note that one directory entry may have several values for the attribute. Intended for role searches and similar scenarios.

Parameters:

base - the DN to search in

filter - search filter to use

params - the parameters to substitute in the search filter

attributeName - the attribute who's values are to be retrieved.

Returns:

the set of String values for the attribute as a union of the values found in all the matching entries.

searchForSingleEntry

public DirContextOperations searchForSingleEntry(String base,
                                        String filter,
                                        Object[] params)

Performs a search, with the requirement that the search shall return a single directory entry, and uses the supplied mapper to create the object from that entry.

Ignores PartialResultException if thrown, for compatibility with Active Directory (see LdapTemplate.setIgnorePartialResultException(boolean)).

Parameters:

base - the search base, relative to the base context supplied by the context source.

filter - the LDAP search filter

params - parameters to be substituted in the search.

Returns:

a DirContextOperations instance created from the matching entry.

Throws:

IncorrectResultSizeDataAccessException - if no results are found or the search returns more than one result.

searchForSingleEntryInternal

public static DirContextOperations searchForSingleEntryInternal(DirContext ctx,
                                                SearchControls searchControls,
                                                String base,
                                                String filter,
                                                Object[] params)
                                                         throws NamingException

Internal method extracted to avoid code duplication in AD search.

Throws:

NamingException

setSearchControls

public void setSearchControls(SearchControls searchControls)

Sets the search controls which will be used for search operations by the template.

Parameters:

searchControls - the SearchControls instance which will be cached in the template.
