I need help on the following

• I have successfully integrated azure AD(cloud) as an IDP
• Connection test from azure AD okta application is successfull
• When I am trying to login to an application in OKTA using my azure AD credentials it is giving Authentication failed error
• I have also created routing rules for IDP. Where I target an application and say anyone logs in to be redirected to that IDP

Not , sure where am i getting wrong. I think okta is not able to recognize the users logging in with AD credetials
