Not getting SP resource after authentication

[Zico]

Hi,

I have a Shib SP 2.5.2 setup and I am trying to SSO with Shib IdP. The issue is,
whenever I am hitting my SP, it is redirecting me to IdP for authentication but
after authentication instead of going to SP page, I am jumped to IdP login
again. I have tried to check all SP logs, but not getting much enough to
troubleshoot. Any kind of hint is appreciated. Just to add: my SP's hostname is
not "https" but it's "http" and SP is in IIS platform.

My SP's shibd.log is showing these:
