SSO issue in Selective AD Trust Environment

hi,

we have selective 2 way trust  between test.ik.net , test1.kb.net . in that, a web application , sso not working in trusted domain , working fine in trusting environment.

dns configuration(source domain):(test.ik.net )

not ad integrated dns

dns namespace: test.ik.net

application hosted different namespace : https://web01.testcorp.net

conditional forwarder configured in test.ik.net to testcorp.net

trusted domain dns configuration:(test1.kb.net )

ad integrated dns

conditional forwarder has been configured test.ik.net dns , 53 port opened

there no port opened trusted domain testcorp.net

proper spn has been configured , users can able access application without sso.

the application hosted test.ik.net namespace working fine both ends, namespace testcorp.net makes sso issue. please suggest reslove issue.

thanks in advance

from i've understood, have set forest trust (not domain trust), because namespace of 2 domains different, it's right?

anyway should verify this 

there no port opened trusted domain to testcorp.net

if understood right, testcorp.net namespace configured on test1.kb.net.
