I'm using Fedora 29 x96_64 fully patched. I'm trying to use my modem without the need for sudo. I should be able to usermod my account and be done with it. $ ls -Al /dev/ttyS0 crw-rw----. 1 root dialout 4, 64 Feb 24 22:23 /dev/ttyS0 SSSD does not allow me to add my account to dialout group. I had to remove SSSD so I could add my account to the dialout group. Something seems amiss since sssd(8) man page says sssd is for mounting remote directories (which I don't do on this machine). $ sudo usermod -a -G dialout jwalton (Sun Feb 24 22:26:35:168766 2019) [sss_cache] [confdb_get_domains] (0x0010): No domains configured, fatal error! Could not open available domains usermod: sss_cache exited with status 2 usermod: Failed to flush the sssd cache. $ sudo dnf remove sssd Dependencies resolved. ================================================================================ Package Arch Version Repository Size ================================================================================ Removing: sssd x86_64 2.0.0-5.fc29 @updates 34 k Removing unused dependencies: adcli x86_64 0.8.2-2.fc29 @fedora 265 k c-ares x86_64 1.13.0-5.fc29 @fedora 221 k cyrus-sasl-gssapi x86_64 2.1.27-0.3rc7.fc29 @fedora 41 k libdhash x86_64 0.5.0-41.fc29 @fedora 60 k libipa_hbac x86_64 2.0.0-5.fc29 @updates 61 k libsss_autofs x86_64 2.0.0-5.fc29 @updates 65 k libsss_certmap x86_64 2.0.0-5.fc29 @updates 119 k libsss_idmap x86_64 2.0.0-5.fc29 @updates 77 k libsss_nss_idmap x86_64 2.0.0-5.fc29 @updates 89 k libsss_sudo x86_64 2.0.0-5.fc29 @updates 58 k python3-sssdconfig noarch 2.0.0-5.fc29 @updates 185 k sssd-ad x86_64 2.0.0-5.fc29 @updates 377 k sssd-client x86_64 2.0.0-5.fc29 @updates 249 k sssd-common x86_64 2.0.0-5.fc29 @updates 4.9 M sssd-common-pac x86_64 2.0.0-5.fc29 @updates 247 k sssd-ipa x86_64 2.0.0-5.fc29 @updates 708 k sssd-krb5 x86_64 2.0.0-5.fc29 @updates 83 k sssd-krb5-common x86_64 2.0.0-5.fc29 @updates 292 k sssd-ldap x86_64 2.0.0-5.fc29 @updates 141 k sssd-nfs-idmap x86_64 2.0.0-5.fc29 @updates 41 k sssd-proxy x86_64 2.0.0-5.fc29 @updates 138 k Transaction Summary ================================================================================ Remove 22 Packages Freed space: 8.4 M Is this ok [y/N]: Y Running transaction check Transaction check succeeded.
