Hi,In the release notes I'm reading the following: Portal User Interface You can now copy and paste a vertical list from Excel to the Resource Picker input box. This is especially useful for doing bulk Adds. The UOC text box now lets you check uniqueness using a custom XPATH statement that you provide. Note This only works in Create mode, not in Edit mode. Attempting this in Edit mode may cause the check to be done when its not intended.Can somebody provide an example how to do that for for example the AccountName attribute?thanks!Jorge de Almeida Pinto [MVP-DS / AD DS TechNet Forums Moderator]

Hi Jorge,You can do this by adding the "UniquenessValidationXPath" property as below, 1. Go to "Resource Control Display Configuration" and choose "Configuration for Group Creation" 2. Click export configuration and save to any location 3. Modify this section by adding the bold line. <my:Control my:Name="Alias" my:TypeName="UocTextBox" my:Caption="{Binding Source=schema, Path=MailNickname.DisplayName}" my:RightsLevel="{Binding Source=rights, Path=MailNickname}"> <my:Properties> <my:Property my:Name="Required" my:Value="true"/> <my:Property my:Name="HintPath" my:Value="Hint"/> <my:Property my:Name="Text" my:Value="{Binding Source=object, Path=MailNickname, Mode=TwoWay}"/> <my:Property my:Name="MaxLength" my:Value="128"/> <my:Property my:Name="RegularExpression" my:Value="{Binding Source=schema, Path=MailNickname.StringRegex}"/> <my:Property my:Name="UniquenessValidationXPath" my:Value="/Group[MailNickname='%VALUE%']" /> </my:Properties> </my:Control> 4. Click on the brows button and choose the modified file and submit the modification. 5. IISRESET.Thanks,Sri

HI Sri,Just tried it. Works like a charm. From a consistency point of view the behavior of this should not only work during creation only, but also during editsCheersJorgeJorge de Almeida Pinto [MVP-DS / AD DS TechNet Forums Moderator]

Hi Jorge,This is currently only supported in Create Mode for FIM 2010.Thanks,Sri

Sri, Are there any plans for enabling the UniquenessValidationXPath for edit mode as well? //henrikHenrik Nilsson Blog: http://www.idmcrisis.com Company: Cortego (http://www.cortego.se)

Henrik,None at this time. I think it will be in consideration for future releases.Thanks,Sri

Ok! Thanks!Henrik Nilsson Blog: http://www.idmcrisis.com Company: Cortego (http://www.cortego.se)

You can limit permissions or the rcdc to make it read only in edit mode and prevent the issue, but yeah I would like that too.David Lundell www.ilmBestPractices.com

I know this is an older thread, but thought I would mention that this change also seems to work in Edit mode now.

Hi, It appears to work but it does not work correctly. You cannot use the same XPATH validation filter from the CREATE mode in the EDIT mode. The XPATH validation filter has to be slightly different!
