IBM Power Ideas Portal


This portal is to open public enhancement requests against IBM Power Systems products, including IBM i. To view all of your ideas submitted to IBM, create and manage groups of Ideas, or create an idea explicitly set to be either visible by all (public) or visible only to you and IBM (private), use the IBM Unified Ideas Portal (https://ideas.ibm.com).

Secure Kerberos keytab file

All single sign on interface can deal with *PUBLIC=*EXCLUDE for the NAS keytab file :
/QIBM/UserData/OS400/NetworkAuthentication/keytab/krb5.keytab

However, if you want to enable SSO for IBM Navigator for i SSO will not work with that specific setting. You must either set *PUBLIC to *R or grant user QLWISVR *R access.

I believe this is a design fault. The underlying Java class Krb5LoginModule (of the IBM JDK) should be able to deal with this. Maybe swap profile or so.


Use Case:

Enable SSO for IBM i Navigator for i without making compromises to /QIBM/UserData/OS400/NetworkAuthentication/keytab/krb5.keytab.

    IBM believes that the request described has been partially solved/delivered. There are technology restrictions for swapping profiles so the best solution is for the IBM Navigator for i profile QLWISVR (which has password *NONE so it can't be used to sign on) to have *R access to the krb5.keytab file. This is more restrictive than giving *PUBLIC *R. The *R access is granted by running with the following PTFs:
    IBM i 7.4 - SI72017 and SI72016
    IBM i 7.3 - SI72015 and SI72014
    IBM i 7.2 - SI72025 and SI72018

    IBM has received the requirement and is evaluating it. IBM will provide a response after evaluation is complete.
