Len,
You can call a class method from an instance just like any other method
with a parameter. So if you might want to consider calling it with the ldap
server as a parameter.
def self.ldap_connection(ldap_host)
Puppet.debug("Creating new LDAP connection")
unless @ldap_connection
@ldap_conection = Net::LDAP.new(
:host => ldap_host,
.......
@ldap_connection
end
and call it from an instance method:
def create ## Instance level method
self.class.ldap_connection(my_ldapserver).add(:dn => mydn, :attributes
=> myattr)
end
Hope this helps.
