Incorrect passive auth URL after changing WsFedPassiveMetadataUri

I have been trying to enable passive authentication on Lync server 2013. Using theSet-CsWebServiceConfiguration I have set UseWsFedPassiveAuth to true as well as settingWsFedPassiveMetadataUri to the metadata URI of the ADFS server. However, I have later found out that theWsFedPassiveMetadataUri was incorrect (meaning the wrong ADFS server, the data in the .xml file itself were correct) and I had to replace it with a correct URI. However, after replacing it, thehttps://.../PassiveAuth/PassiveAuth.aspx link is still pointing to the old login page.

Is there some way how to "refresh" it? I tried restarting the Lync server, but that didn't help.

Thanks any suggestion or hint is welcomed.

PS. when I manually modify the PassiveAuth.aspx file and I use .Replace method to replace the wrong login page domain to the correct one (so.Replace("login-wrong.example.com", "login-correct.example.com")), everything works as it should.
