Treequel is an LDAP toolkit for Ruby. It is intended to allow quick,  
easy  
access to LDAP directories in a manner consistent with LDAP’s  
hierarchical,  
free-form nature.

It’s inspired by and modeled after Sequel  
([http://sequel.rubyforge.org/](http://sequel.rubyforge.org/)), a  
kick-ass database library.

== Examples

Here are a few short examples to whet your appetite:

# Connect to the directory at the specified URL

dir = Treequel.directory( ‘ldap://ldap.company.com/dc=company,dc=com’  
)

# Get a list of email addresses of every ‘person’ in the directory

that

# has one

dir.filter( :objectClass =\> :person ).filter( :mail ).map( :mail  
).flatten

# Get a list of all IP addresses for all hosts in any ou=hosts group

# in the whole directory:

dir.filter( :ou =\> :hosts ).collection.filter( :ipHostNumber ).  
map( :ipHostNumber ).flatten

# Get all people in the directory under ou=people in the form of a

hash of

# names keyed by email addresses

dir.ou( :people ).filter( :mail ).to\_hash( :mail, :cn )

More elaborate examples of real-world usage can be found in the  
examples/  
directory in the distribution. You can also browse them in a web browser  
via the project page:
