Cannot Load Active Directory Security Groups using AuthAnvil Logon Configuration Tool


When starting the AuthAnvil Logon Configuration tool, the SAS URL and Site ID are displayed, but the Override Group dropdown is not populated, and the error message

"Error trying to read logon keys. Error: Unknown error (0x80005000)"



One of the OUs or Security Groups in Active Directory has a forward slash (/) in the name, which causes the tool to be unable to parse the names of groups. This causes the tool to fail with the above error.



Renaming the OU or group will resolve the error.

 Note: To search for the OU or group that contains the forward slash, consider running the following PowerShell scripts:


Import-module ActiveDirectory

Get-ADOrganizationalUnit -Filter {Name -like "*/*"}

Get-ADGroup -Filter {Name -like "*/*"}


This will import the ActiveDirectory PowerShell module, allowing you to run the second and third command to search for names with forward slashes.




AuthAnvil Windows Logon Agent and Credential Provider 4.0.0.x and earlier.
