public class ScriptableJndiServices
extends ScriptableObject

Simple interface to some methods to access an LDAP directory.

This class is available as "ldap" or "srcLdap" in several JavaScript enabled parameters in the LSC configuration. The methods allow you to interact with an LDAP directory.

Based on Rhino (JavaScript interpreter), this class is able to understand your LQL requests.

All methods in the class use methods from JndiServices.

Tests if an entry exists with the given DN and if it matches a given LDAP filter.

Parameters:

dn - The DN of the entry to check.

filter - The LDAP filter to check on the above DN.

Returns:

List List containing the DN if it exists and matches the filter, or null otherwise.

Throws:

NamingException

exists

public final List<String> exists(Object dn)
                          throws NamingException

Tests if an entry exists with the given DN.

Parameters:

dn - The DN of the entry to check.

Returns:

List List containing the DN if it exists and matches the filter, or null otherwise.

Throws:

NamingException

or

public final List<String> or(Object a,
                             Object b)
                      throws NamingException

Performs a union on two Lists of Strings.

Parameters:

a - List of Strings

b - List of Strings

Returns:

List List of Strings containing all elements from a and b.

Throws:

NamingException

attribute

public final List<String> attribute(Object base,
                                    Object attrName)
                             throws NamingException

Reads the entry given by a DN, and returns the values of the given attribute.

Parameters:

base - The DN of the entry to read.

attrName - The name of the attribute to read.

Returns:

List List of values of the attribute, as Strings.

Throws:

NamingException

and

public final List<String> and(Object a,
                              Object b)
                       throws NamingException

Performs an intersection on two Lists of Strings.

Parameters:

a - List of Strings

b - List of Strings

Returns:

List List of Strings containing elements that are in both a and b.

Throws:

NamingException

retain

public final List<String> retain(Object a,
                                 Object b)
                          throws NamingException

Removes all elements of a List of Strings b from a List of Strings a.

Parameters:

sup

public final List<String> sup(Object dn,
                              Object level)
                       throws NamingException

Returns the parent DN on the n-th level of a given DN, in a List of Strings.

For example, given ("uid=1234,ou=People,dc=normation,dc=com", 2), returns "dc=normation,dc=com" (in a List of Strings).

As a special case, if the requested level is 0, the result is a List of the given DN and all it's parent DNs until the context DN. In the above example, this List would be ["uid=1234,ou=People,dc=normation,dc=com", "ou=People,dc=normation,dc=com", "dc=normation,dc=com"], assuming that the context DN is "dc=normation,dc=com".

This method returns null if a negative level is given.

Parameters:

dn - The DN whose parent we want.

level - The number of levels to go up, or 0 to return all parent DNs.

Returns:

List List containing the parent DN, or all parent DNs if level is 0, or null if level is negative.

Throws:

NamingException

fsup

public final List<String> fsup(Object dn,
                               Object filter)
                        throws NamingException

Returns a List containing the given DN and all parent DNs that exist and match a given LDAP filter.

This method returns the same result as sup(dn, 0), with validation that each object exists and matches the given filter.

Parameters:

dn - The DN whose parents we want.

filter - The LDAP filter to check.

Returns:

List List of DNs as Strings that are this entry's DN, or it's parents DN, that exist and match the given filter.

Throws:

NamingException

getContextDn

public String getContextDn()

Get the context DN configured for this instance.

Returns:

The context DN as a String.
