Entra ID (VA) connector - Provisioning multi-valued extension attributes

[jesvin90 (Jesvin Joseph)]

Hi Experts,

Has anyone done a multi-valued, Custom (Extension) Attribute provisioning in Azure AD/Entra through ISC.? I end up having extra square brackets added to the attribute value.

The Identity attributes are pipe separated (eg. 300312|999123) and the provisioning policy is setup as below :

{
            "name": "extension_xxxxxxxxxxxxxxxxxx35c97_businessCategory",
            "transform": {
                "type": "identityAttribute",
                "attributes": {
                    "name": "multivalues"
                }
            },
            "attributes": {
                "cloudDelimiter": "|"
            },
            "isRequired": false,
            "type": "string",
            "isMultiValued": true
        },

The attribute is populated with extra brackets as seen in the below snippet :

The account schema attribute is marked multi-valued as well.
