Groovy LDAP access

Groovy script to access and modify LDAP or Active Directory using groovy ldap library.

Need following library:

groovy-ldap.jar

Class loading:
this.getClass().classLoader.rootLoader.addURL(new File("lib/groovy-ldap.jar").toURL()); import org.apache.directory.groovyldap.*;

Connecting LDAP:
LDAP = Class.forName("org.apache.directory.groovyldap.LDAP"); SearchScope = Class.forName("org.apache.directory.groovyldap.SearchScope"); host = "<ldap_host_addr>"; ad_user = "<ldap_priv_userid>"; ad_password = "<password>"; ldap = LDAP.newInstance(host, ad_user, ad_password); println "Connected to AD => $host";

Reading an entry:
search_str = "uid=<uid_info>*"; //* regex match entries = ldap.search(search_str, "<ldap_ou_path>", SearchScope.ONE); print "${entries.size} entries are found\n\n"; for (entry in entries) { print """ DN: ${entry.dn} Common name: ${entry.cn} uid: ${entry.uid} Object classes: ${entry.objectclass} """ }

Modify an entry:
//user dn is needed; it wont modify cn dn = "<dn_of_entry_to_be_modified>"; mods = [ ["REPLACE", [<field_name_1>: "<new_value_1>"]], ["REPLACE", [<field_name_2>: "<new_value_2>"]], ["ADD", [<new_field>: "<new_value>"]] ] ldap.modify(dn, mods); print "LDAP entry modified\n";
