If you are using SSSD to connect your linux box to AD then you might need to reset the cache that is used with mapping ids (uid and guid) to AD. If so here is quick set of commands to help do exactly that
systemctl stop sssd &&
rm /var/lib/sss/{db,mc}/* &&
sss_cache -E &&
# optionally clear debug logs &&
truncate -s 0 /var/log/sssd/*.log &&
systemctl start sssd
