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).

IBMi request new Kerberos ticket

With Enterprise Identity Mapping (EIM) and Kerberos, Windows clients can authenticate to IBMi without supplying a user and password. When the client connects, it supplies IBMi with a Kerberos ticket for authentication.

A Kerberos ticket has a fixed lifespan (the default for Windows Active Directory is 10 hours). After the Kerberos ticket expires, the Windows client requests a new ticket from Active Directory. IBMi does not request a new ticket from the Windows client. IBMi should request the updated ticket.


Use Case:

Like most IBMi shops, we run also run Windows servers. We use the QNTC file system to access files on Windows shares. This works fine with Kerberos until the ticket expires. At that point, the QNTC requests are rejected and errors are generated. This causes outages within the apps that rely on QTNC. If IBMi requested a new ticket, the apps would continue working and the users wouldn't experience app outages.

    While we don't disagree with the request, we won't be able to get to this one within the next two releases due to other priorities, so we are declining it now.

    IBM will use this request as input to planning but no commitment is made or implied. This request will be updated in the future if IBM implements it. IBM will use votes and comments from others in the community to help prioritize this request.

    The CAAC has reviewed this requirement and recommends that IBM view this as a high priority requirement that is important to be addressed. More folks are using Kerberos these days, so IBM i needs to make it more automated to keep it active for long-running needs. If the industry standard is to request a new ticket, IBM i should do that to support an improved user experience.

    Background: The COMMON Americas Advisory Council (CAAC) members have a broad range of experience in working with small and medium-sized IBM i customers. CAAC has a key role in working with IBM i development to help assess the value and impact of individual RFEs on the broader IBM i community, and has therefore reviewed your RFE.

    The COMMON Europe Advisory Council (CEAC) has reviewed this requirement and recommends that IBM view this as a medium priority requirement that should be addressed.

    Background: The CEAC members have a broad range of experience in working with small and medium-sized IBM i customers. CEAC has a crucial role in working with IBM i development to help assess the value and impact of individual RFEs on the broader IBM i community and has therefore reviewed your RFE.

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