UC Berkeley LDAP

UCB::LDAP is a wrapper module around Net::LDAP intended to simplify searching the UC Berkeley LDAP directory: directory.berkeley.edu

Introduction to LDAP

If you are blissfully ignorant of LDAP, you should familiarize yourself with some of the basics. Here is a great online resource: www.zytrax.com/books/ldap

The RDoc for the ruby-net-ldap Gem (rubyfurnace.com/docs/ruby-net-ldap-0.0.4/classes/Net/LDAP.html) also has a good introduction to LDAP.

Examples

General Search

Search the directory specifying tree base and filter, getting back generic UCB::LDAP::Entry instances:

entries = UCB::LDAP.search(:base => "ou=people,dc=berkeley,dc=edu", :filter => {:uid => 123}
entry.uid             #=> '123'
entry.givenname       #=> 'John'
entry.sn              #=> 'Doe'

See UCB::LDAP::Entry for more information.

Person Search

Search the Person tree getting back UCB::LDAP::Person instances:

person = UCB::LDAP::Person.find_by_uid("123")
person.firstname           #=> "John"
person.affiliations        #=> ['EMPLOYEE-TYPE-STAFF']
person.employee?           #=> true
person.employee_staff?     #=> true
person.employee_academic?  #=> false
person.student?            #=> false

See UCB::LDAP::Person for more information.

Org Unit Search

Search the Org Unit tree getting back UCB::LDAP::Org instances:

dept = UCB::LDAP::Org.org_by_ou 'jkasd'
dept.deptid         #=> "JKASD"
dept.name           #=> "Administrative Systems Dept"

See UCB::LDAP::Org for more information.

Privileged Binds

If you want access the directory anonomously, no credentials are required. If you want to access via a privileged bind, authenticate before querying:

p = UCB::LDAP::Person.find_by_uid("123")
p.non_public_attr    #=> NoMethodError
UCB::LDAP.authenticate("mybind", "mypassword")
p = UCB::LDAP::Person.find_by_uid("123")
p.non_public_attr    #=> "some value"

Privileged Binds and Rails
