[CLOSED] Issues Implementing SSO on Linux using Kerberos
Hi,
We are trying to Implement SSO USING TOMCAT/IIS/KERBEROS Authentication on WebFOCUS 8.2.04 on Linux OS using the instructions provided in the WebFOCUS Security and Administration Manual and we are getting the following error
'Cannot create inner bean 'com.ibi.webapp.security.kerberos.WFKerberosTicketValidator#2abc4d56' of type [com.ibi.webapp.security.kerberos.WFKerberosTicketValidator] while setting bean property 'ticketValidator'; '

Just Wondering If anybody has already Implemented SSO using Kerberos on Linux and could share their experience or notes would be helpful.
Thanks
Kiron

Have you updated your krb5-ini file to specificy encryption type?

Yes,
we updated the krb5.conf file with the correct Encryption Type.

I found this on techsupport. I hope it helps.

Solution Notes
Symptom


Kerberos authentication fails with error message in websecurity.log:

Error creating bean with name 'com.ibi.webapp.security.kerberos.WFKerberosTicketValidator#62e81ae5' defined in ServletContext resource [/WEB-INF/was/security-main.xml]: Invocation of init method failed; nested exception is javax.security.auth.login.LoginException: Do not have keys of types listed in default_tkt_enctypes available; only have keys of following type: AES256 CTS mode with HMAC SHA1-96

Problem


The krb5.ini file did not specify the correct encryption type. The error message is indicating it is missing aes256-cts-hmac-sha1-96 encryption type.

Solution


Update the krb5-ini file to specificy encryption type aes256-cts-hmac-sha1-96.

before update:

default_tkt_enctypes = aes128-cts-hmac-sha1-96
default_tgs_enctypes = aes128-cts-hmac-sha1-96

After update:

default_tkt_enctypes = aes256-cts-hmac-sha1-96
default_tgs_enctypes = aes256-cts-hmac-sha1-96

Thanks for the information. We are currently using aes256 in the krb5.conf file and that matches our Keytab file encryption.

That was all I could find.. Unless someone else chimes in I think you should open a case with techsupport.
