[activeldap-discuss] Moving Objects To New Container

Fri Apr 16 18:29:09 EDT 2010

I took a look at Alexey's Ruby/LDAP code on github.  No idea if this would work....but the PERL examples I've seen put newsuperior before deleteoldrdn in the params list.  Just wondering if all it takes is a patch submission?

Thanks,
Matt

Say I have this object: 

user.cn = USERA 
user.dn = CN=USERA,OU=OLDOU 

...and I want to move this object to a new ou of OU=NEWOU. I see these two methods... 

modify_rdn (dn, new_rdn, delete_old_rdn, new_superior, options={}) 
modify_rdn_entry (dn, new_rdn, delete_old_rdn, new_superior, options={})

Something like this...??

user = User.find("USERA")
user.modify_rdn("CN=USERA,OU=OLDOU", "CN=USERA", true, "OU=NEWOU", {})
user.save

However...  modify_rdn gives me...
"undefined method `modify_rdn' for #<User:.....>"

...and modify_rdn_entry gives me...
"not implemented:  modify RDN with new superior"

Looks like this is currently not possible with ActiveLdap....or is there another way?

Thanks,
Matt

Subject: [Ruby-activeldap-discuss] I'm having fun with ActiveLdap::DistinguishedName class... 

I want to move an object from its current container into a sub container (ou=toBeDeleted) and this would seem to be the way to do it... 

modify_rdn(dn, new_rdn, delete_old_rdn, new_superior, options={}) 

now, I have the dn. The new rdn, would be "cn=old cn", so that isn't a problem. delete_old_rdn is true, so that isn't a problem. The issue is new_superior. I need to take the cn off the front of the DN, and replace it with the new OU. 

I thought it would be great to make use of activeLdap's DistinguishedName handler to save me the problem of rolling my own DistinguishedName parser. 

ActiveLdap::DistinguishedName.parse( my_object.dn ) does just what I'd expect. I can then look at the .rdns value and use strip to get rid of the cn on the end. I can add { "ou" => "toBeDeleted" } to the start of the array, but then I can't get the resultant array of hashes back into an ActiveLdap::DistinguishedName type and from there back into a string. 

>> arr 
=> [{"CN"=>"Computers"}, {"dc"=>"ads"}, {"dc"=>"blah"}, {"dc"=>"com"}] 
>> newdn.rdns = arr 
NoMethodError: undefined method `rdns=' for #<ActiveLdap::DistinguishedName:0xb292c @rdns=[]> 
from (irb):74 
>> 

>> ActiveLdap::DistinguishedName.new(arr) 
=> #<ActiveLdap::DistinguishedName:0x45ae854 @rdns=[[{"CN"=>"Computers"}, {"dc"=>"ads"}, {"dc"=>"blah"}, {"dc"=>"com"}]]> 
>> ActiveLdap::DistinguishedName.new(arr).to_s 
NoMethodError: undefined method `upcase' for {"CN"=>"Computers"}:Hash

The reason that the second method fails is rdns ends up wrapped in another array. The following change would fix the problem, but the behaviour of ActiveLdap::DistinguishedName.new( ["cn","anything"] ) would change.... 

file: distinguished_name.rb 

def initialize(*rdns) 
if rdns.size == 1 and rdns[0].is_a?(Array) 
rdns = rdns[0] 
end 
@rdns = rdns.collect do |rdn| 
if rdn.is_a?(Array) and rdn.size == 2 
{rdn[0] => rdn[1]} 
else 
rdn 
end 
end 
end 

Is there any really easy way to make the parser do what I want?
