Hi all, For some reason, for a particular user, sss_ssh_authorizedkeys is extremely slow on the IPA-server: time /usr/bin/sss_ssh_authorizedkeys <username>~real 0m9.520suser 0m0.022ssys 0m0.018s It will return all the public keys, but is is slow, causing SSH-login delays using a ssh-keys. On another CentOS Stream (8.1) IPA-client, using the same IPA-server: time /usr/bin/sss_ssh_authorizedkeys <username>~real 0m0.020suser 0m0.005ssys 0m0.003s Some difference...Adding "certificate_verification = no_ocsp" to sssd.conf on the IPA-server will bring back performance, but sound like a poor workaround. Any idea what is happening here?
SSSD picks up certificates associated with the user entry for use as SSH keys as well. I guess verification of those certificates via OCSP takes time and that's why switching off the verification helps. -- / Alexander Bokovoy Sr. Principal Software Engineer Security / Identity Management Engineering Red Hat Limited, Finland _______________________________________________ FreeIPA-users mailing list -- freeipa-users@lists.fedorahosted.org To unsubscribe send an email to freeipa-users-le...@lists.fedorahosted.org Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedorahosted.org/archives/list/freeipa-users@lists.fedorahosted.org
