[Xymon] status of disabled alert shows Disabled by: unknown @

Good day

I am using the Terabithia repo for my Xymon instance.

All is working great an so far no major issues. Only problem I am struggling with is when I disable a alert the status show -

Disabled until OK Disabled by: unknown @ 172.33.255.1 Reason: investigating

Where do I need to change to display the name of the authenticated user @ source ip.

Authentication is handled by apache basic authentication.

Kind regards
