 += Identity Manager and Converting Multi-Valued Attributes to Single-Valued Attributes =
 +This is an article on how to combine multiple values from a multi-valued attribute into a single valued attribute. This is required when you have multiple values in for example the Location or Room Number in eDirectory.
  
 += Symptom =
 +We are first going to see what goes wrong:
 +== One value ==
 +When we populate the location field in iManager for a synchronized user the value gets synced as well:
 +Enter the single value in iManager:
 +{{idmmultivalue01.jpg}} \\
 +And the value get synced to Active Directory:
 +{{idmmultivalue02.jpg}} \\
 +== Two values ==
 +Now we first remove the original value (make sure the removal of the attribute gets synchronized) and then add two values to the attribute:
 +{{idmmultivalue03.jpg}} \\
 +But the value doesn'​t sync through:
 +{{idmmultivalue04.jpg}} \\
 +But in the dstrace log we see an error:

 += Solution =
 +To solve this issue we need to create a new policy, and in that policy we have to create three rules:
 +* Setup Local Variable
 +* Concatenate Values
 +* Remove Values If Needed
 +
 +First I'll show you each rule individually and after that the end result.
 +
 +== Create Policy ==
 +The policy has to be created in the "Event Transformation Policies":​
 +{{idmmultivalue05.jpg}} \\
 +Click '​Insert'​ and provide the required values:
 +{{idmmultivalue06.jpg}} \\
 +
 +== Setup Local Variable ==
 +We first create a simple rule that creates a local variable that is a nodeset of the L (location) attribute:
 +{{idmmultivalue07.jpg}} \\
 +
 +== Concatenate Values ==
 +The second rule is a bit more complex. The conditions are still simple:
 +{{idmmultivalue08.jpg}} \\
 +
 +But the actions are a bit more complicated. Below I show you first the complete action list, and then I explain the first and third one a bit more in depth:
 +{{idmmultivalue09.jpg}} \\
 +
 +The first action is not even entirely visible. Click on the 'Edit the Actions'​ button. Now you see that 'for each' value you create a local variable called lvlocationoffice:​
 +{{idmmultivalue10.jpg}} \\
 +
 +And again, this time the arguments, are not entirely visible. Click on the 'Edit the arguments'​. Here you set the variable to itself, followed by a comma, a space, and a special value called '​current-node'​. The current-node is the attribute value for the specific increment the loop is on:
 +{{idmmultivalue11.jpg}} \\
 +\\
 +The third actions needs a more in depth view of the arguments, if you click 'Edit the arguments'​ you can edit the verb '​Replace First'​. Don't forget that you're replacing a comma and a space:
 +{{idmmultivalue12.jpg}} \\
 +
 +== Remove Values If Needed ==
 +Needed in case it's a "​remove all values"​ event":​
 +{{idmmultivalue13.jpg}} \\
 +
 +== End Result ==
 +=== iManager view ===
 +{{idmmultivalue14.jpg}} \\
 +=== XML ===

 +== Test ==
 +Now the values in eDirectory give these values in Active Directory:
 +{{idmmultivalue15.jpg}} \\
 +But also, these values sync back:
 +{{idmmultivalue16.jpg}} \\
