Re: officelocation property from asp.net
Hi Joe,
Thanks a lot for the reply.
I have taken your comments about code efficiency on board and will implement
all of you suggestions.
The code I am using is running on a windows 2003 server.
I have been assured by our network people that the "OfficeLocations"
property does exist in the schema and they insist that they have not added
this property to the schema.
The code below (VB script) does grab this property, so it can be obtained
from vb script but I can't find how to get it from .net.
However from what I can gather about this property, it is not returned as a
single value, it is returnd as a "C struct" becuase there can be more that
one office location assosiated with a user!! so i guess it has to be
assosited with some sort of array object..
If you could shed any more light on this for me then I would appreciate it.
one interesting point is that the VB Script code below returns the users
full name as "FullName" where as my .net code returns the same property as
"DisplayName" as maybe there is some discrepancy in naming.
cheers
martin.

Re: officelocation property from asp.net
There is a confusion in terms here. OfficeLocations is an ADSI property on
the IADsUser interface, but it isn't an actual attribute in AD. You can
verify this for yourself by pulling up ldp.exe and doing a search in the
schema container for an object with ldapDisplayName=OfficeLocations. You
won't find it. Additionally, if you pull up any user in your AD with
ldp.exe or ADSI Edit, you won't see OfficeLocations in the returned result.
I can confirm with certainty that the actual AD attribute name is
physicalDeliveryOfficeName. I just checked the MS source code to be sure.
While it is possible to call the IADsUser property methods from .NET (link
here: ), you wouldn't want to do it this way because it forces you to bind
to the object.
Regarding the question about arrays, attributes in AD can be single or
multivalued. In order to implement a general API for handling both, they
are all treated as multi-valued in S.DS.
Thus, the correct pattern for dealing with this in C# would go something
like:
searcher.PropertiesToLoad.Add("physicalDeliveryOfficeName");
SearchResultCollection results;
using (results = searcher.FindAll())
{
foreach(SearchResult result in results)
{
string office;
if (result.Properties.Contains("physicalDeliveryOfficeName"))
office = (string) result.Properties["physicalDeliveryOfficeName"][0];
}
}

Re: officelocation property from asp.net
Hi joe,
many thanks again for the reply.
I will propabally get a chance to try this over the weekend and I will let
you know how it goes.
regarding your email,
how did you manage to "check the MS source code to be sure"
is this something that I can do and is this source code publically
availible????
also you refer to a link
> While it is possible to call the IADsUser property methods from .NET (link

is it possible to let me know this link.
again, many thanks for your help.

Re: officelocation property from asp.net
Hi Martin,
Here was the link:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/sds/sds/invoking_adsi_properties.asp?frame=true
It is a little messy, but it works. There is an easier syntax in .NET 2.0.
Sorry for forgetting that. :)
The source code access is a special MS program that is not open to the
public. Maybe someday. MS doesn't let me post source code, but I am
allowed to do what I just did was to verify something and report back to
you. Maybe someday MS will expand this program to a wider audience.
They've made a lot of progress in the last few years on opening up the
source, but there is still a ways to go for sure.
