Ah, this seems to be an issue with MacOS. In MacOS we have "Credentials cache: API:6136D20A-21F8-4FF3-B968-A4415990AFF1" (this is the uuid of a dynamic API that is used to access the ticket cache). When it succeeds (I assume not on MacOS but likely Linux) we have "Ticket cache: FILE:/tmp/krb5cc_26010" which is the expected response for Linux. I am not familiar with how MacOS handles KB5 tickets but it's an interplay between the keychain and your application. There is some interesting information in https://stackoverflow.com/questions/58653482/what-is-the-default-kerberos-credential-cache-on-osx which also shows you how to create a Linux type ticket cache. -- Reply to this email directly or view it on GitHub: https://github.com/xrootd/xrootd/issues/1981#issuecomment-1486897881 You are receiving this because you are subscribed to this thread.
