SAML Single SIgn On with ADFS , mobile app auth doesn't work

Question

Hi All, 
 we have configured SAML with ADFS 
 Single Sign On works fine by PC but the authentication by mobile app is not possible 
 If we try to connect to the server we see only a blank page into the mobile app 
 
 Any suggestion ? 
 
 Thanks 
 Elia

Hi Joanneh, from your screenshot, you don't seem to be on version 17.x. Are you on 16.x? 
 I was just being told that Appian only started to support "pop-up based authentication" from 17.1 and above and you should be able to see an additional "Identity Provider uses NTLM Authentication" checkbox in the SAML authentication page in Appian Administrator Console. 
 
 After checking the checkbox, I am able to get my iOS app to work now. 
 
 Hope this helps.
