shibboleth logout doesn't redirect

[Bezpaltchikov, Alexei V]

I need to logout from Shibboleth and get redirected back to my landing page. (I understand difference between global and local logout. Local is enough for me.)

I have tried links like these:
    https://localhost/Shibboleth.sso/Logout?return=https://localhost/myMightyApp
    https://idp.myMightyOrg.com/idp/profile/Logout?return=https://localhost/myMightyApp
But both leave me at the
    https://idp.myMightyOrg.com/idp/profile/SAML2/Redirect/SLO?execution=e4s1
          Logout Complete page. 

However, if I use for example Google as return parameter I get an error saying unacceptable redirect location. Also if I use those links when not being logged in, I do get redirected to my application. This tells me that IDP does see my Return parameter.

Is it possible to suppress Logout Complete page and get redirected back to my website landing page? Is there a setting somewhere in the shibboleth2.xml?

Thank you!
Alexei.
