  • Hi ,

    I have a MIM server where I saw the below error.

    Event ID :1000

    Event Description: Faulting application name: miiserver.exe, version: 4.1.3733.0, time stamp: 0x56edbcbe

    Upon checking the issue I found ADMA and another MA  which runs after ADMA,throws error "extension-unexpected-attribute-value" during sync.And stack trace shows below error.

    Synchrozization Step : Provisioning

    Extension Name : MV Router.dll

  • Your MV Rules extension is attempting to provision an account with a DN that already exists in the directory. You'll need to code around this possibility by using try catch and perhaps appending a number onto the DN if the exception is thrown. It could also be a data issue where something that you thought would be unique on the source side is not. In this case you need to improve controls around data quality in the source systems.
