Signed Powershell Scripts not running



My code signed EXEs run without and issue, but my signed PS scripts get blocked.  Can someone please confirm whether MAC support signed PS scripts.

Re: Signed Powershell Scripts not running

What error message do you see in your s3diag or solidcore log when trying to run signed powershell.


Also can you give "sadmin ls -lax <path\powershell.ps1>" output

Re: Signed Powershell Scripts not running

Thanks for the quick reply Benjamin.  When running the signed powershell script, the event shown in Solicore is a Prevented File Execution.


I ran the "sadmin ls -lax <path\powershell.ps1>" output command on our signed PS script and the output is below.  It looks like MAC is unable to recognise the code signing cert within the PS script based on that output.  I also ran the same command on one of our signed EXEs, and it clearly identifies our cert.  Windows recognises our signed PS scripts as having a digital signature, when you right click on them and go to properties.

Output of sadmin ls may take some time as certificate extraction is in progress.
