User GUID in SPML response

Question

Hi guys,

We would like to store the user's GUID (after user creation through web services) to be able to query the user afterwards.

How to interpret the value returned in SPML answer ? It's not in the same format than in AD and it seems not possible to use it to lookup the user

<attr name="objectGUID" xmlns="urn:oasis:names:tc:DSML:2:0:core">
<value>F4c9c6PjOUKxMyIfXuYoNw==</value>
</attr>

Thanks for your help

Regards

Hello,

The thing is that object GUIDs are stored in Active Directory in binary form, as an array of byte (Byte[]). The SPML protocol allows exchanging data in the form of XML documents, which are text only. Thus, to represent a binary value in text form, it is converted into a Base64 string. You can use the Convert.FromBase64String method in your code to get the binary value of the object GUID.
