In order to accomplish using SAML Authentication via Vidyo Desktop Window (Not in External Browser), a registry or plist entry needs to be added.
On windows set registry:
[HKEY_CURRENT_USER\Software\Vidyo\VidyoDesktop3\external] "AuthenticationMethod"="SAML" "SAMLAuthenticationURL"="https://saml1.support.com"
On Mac set plist:
*Download xCode from the AppStore*
Under ~/Library/Preferences/ (click on Go – hold option key – while holding click on the new line Library, after that open the preference folder)
Open the following plist files with xCode.
In plist - com.vidyo.VidyoDesktop3.plist - the following keys should be updated
external.AuthenticationMethod = SAML (empty for portal/LDAP)
external.SAMLAuthenticationUrl = <tenetURL enabled with SAML>
external.AuthenticationMethod = SAML
external.SAMLAuthenticationUrl = https://saml1.support.com
Please remember to quit VD before and refresh plist cache after editing (in terminal run the following command - defaults read ~/Library/Preferences/com.vidyo.VidyoDesktop3.plist)
