Hi Madhu,
1. Default role will go to path with no stages and will wait until end of request then it will provision once my main path gets approved at all stages. For this my provisioning settings should be "END OF REQUEST". If i maintain them as "END OF PATH", default role, since it is in a path with no stages it directly tries to provision and fails as the user is not yet created. [User creation will happen through main path]. Hence i used END OF REQUEST setting and then issue was resolved for this scenario.
In the "Global Provisioning Configuration" under option "Create user if does not exist" check the box "For Assign Role Action" and maintain the provisioning options to be "Auto provisioning at end of path". When default role with no approval required this will create a user ID with the default role and will not wait of the main path for user ID creation
For stage 3 anyways you need to set the "End of Path"
Try this and let me know.

Muthu
