Hi,
I can see few things in Global properties.
keytab file path you are including in Global properties and updating Java config in Tomcat with serviceaccount pwd.
1)
idm.keytab=C:/Windows/keytabfilename.keytab
idm.allowS4U=true
2)
-Dcom.wedgetail.idm.sso.password=
you have to use anyone of this.
Remove the below line from Global properties and restart the tomcat.
idm.keytab=C:/Windows/keytabfilename.keytab
idm.allowS4U=true
Let me know if you still have the issue.
