While logging into the BI launchpad after configuring the BOBJ server, it throws the below error.
HTTP Status 500 – com.wedgetail.idm.sso.ProtocolException: com.wedgetail.idm.spnego.server.SpnegoException: GSSException:
Failure unspecified at GSS-API level (Mechanism level: com.dstc.security.kerberos.KerberosException:
Successfully matched service principal “XXXXXX” but not key type (18) + KVNO (4) in this entry: Principal:  XXXXXX
TimeStamp: Thu Jan 01 01:00:00 GMT 1970 KVNO: -1 EncType: 23 Key: 16 bytes, fingerprint = [97 34 3b e6 82 44 5f fc cf 24 a3 a8 d2 c8 f1 94] )
The BOBJ server was a image copy of another BOBJ server and hence the SPN and Kerbros keytab files were already configured with SSO. But in the new system since the SPN and keytab entries are not set up, these old entries along with SSO enabled set up will not work. It will always throw this error, when we try to launch BI launchpad.
Need to set SSO.Enabled=false in Global.Properties file at installation directory\tomcat\webapps\BOE\WEB-INF\config\custom .
After setting , need to restart Tomcat to get the changes in effect.
Hope this helps..
