[SSSD-users] Does sssd use initgroups?

All, sssd front-end, AD back-end. Does sssd use initgroups to use initial group membership? I was recently debugging a sssd connection problem in the /var/log/sssd/sssd* logs (debug level 9). and I thought I saw a reference to initgroups. or getgrouplist(). my /etc/nsswitch.conf file has: passwd: files systemd sss group: files systemd sss Should I also have a line with: initgroups: files systemd sss Spike White
