"kinit -k" (with no arguments) defaults to attempting to obtain a TGT for (e.g.) host/mymachine.example....@example.org, which only works if you set userPrincipalName to host/mymachine.example....@example.org when you joined the host to Active Directory. Running "kinit -k MYMACHINE\$" (that is, using the value of the sAMAccountName attribute as the argument to "kinit -k") should always work. > From what I have read, SSSD is responsible for being the glue between > MIT Kerberos (what Linux uses) and Microsoft Kerberos (which Active > Directory uses). This has nothing to do with sssd; it's all about setting userPrincipalName correctly when you join the host to AD if you want "kinit -k" (with no arguments) to work. _______________________________________________ sssd-users mailing list -- sssd-users@lists.fedorahosted.org To unsubscribe send an email to sssd-users-le...@lists.fedorahosted.org Fedora Code of Conduct: https://usg02.safelinks.protection.office365.us/?url=https%3A%2F%2Fdocs.fedoraproject.org%2Fen-US%2Fproject%2Fcode-of-conduct%2F&data=02%7C01%7C%7Cfc44b59ef54b4f35311508d8344620e5%7Cfae7a2aedf1d444e91bebabb0900b9c2%7C0%7C0%7C637316823113865460&sdata=9uYFM8UBNAY2btttsNdOcxVHn4HoPsq16EGZIT8%2BzxA%3D&reserved=0 List Guidelines: https://usg02.safelinks.protection.office365.us/?url=https%3A%2F%2Ffedoraproject.org%2Fwiki%2FMailing_list_guidelines&data=02%7C01%7C%7Cfc44b59ef54b4f35311508d8344620e5%7Cfae7a2aedf1d444e91bebabb0900b9c2%7C0%7C0%7C637316823113865460&sdata=u%2BYWfJajDCG%2F5GR1mt8kmKtzJPb1bcAr7bYSNrMNHzI%3D&reserved=0 List Archives: https://usg02.safelinks.protection.office365.us/?url=https%3A%2F%2Flists.fedorahosted.org%2Farchives%2Flist%2Fsssd-users%40lists.fedorahosted.org&data=02%7C01%7C%7Cfc44b59ef54b4f35311508d8344620e5%7Cfae7a2aedf1d444e91bebabb0900b9c2%7C0%7C0%7C637316823113865460&sdata=%2FL0QIhBxCfu80Q4FO3SwWdXW0XYP6jo8GpIyoA1uBsw%3D&reserved=0
