Get-AdmPrincipalGroupMembership always throws an exception, even for users which absolutely exist (eg: piped directly from Get-AdmUser)

Example Get-AdmPrincipalGroupMembership -Identity 'Test.User' -AdaxesService localhost

Get-AdmPrincipalGroupMembership : The given key was not present in the dictionary.
    + CategoryInfo          : NotSpecified: (:) [Get-AdmPrincipalGroupMembership], KeyNotFoundException
    + FullyQualifiedErrorId : Softerra:Adaxes:PowerShellModule:Commands:GetAdmPrincipalGroupMembershipCommand:ProcessRecord,Softerra.Adaxes.PowerShellModule.Commands.GetAdmPrincipalGroupMembershipCommand

Unfortunately, this is a known issue in Adaxes 2023 when you use Get-AdmPrincipalGroupMembership with the -AdaxesService parameter. It will be fixed in the upcoming release. We apologize for the inconveniences.

As of now, the only solution is to use the cmdlet without the parameter.


Hello Matt,

A new version of Adaxes containing a fix for the issue is released. You can download it from here.
