Description of problem: When using sssd's files provider, but storing the files in the same location that nss-altfiles uses (/usr/lib) sssd needs the ability to set an inotify watch on /usr/lib Version-Release number of selected component (if applicable): selinux-policy-37.19-1.fc37.noarch How reproducible: 100% Steps to Reproduce: 1. deploy passwd/group for use with nss-altfiles 2. configure sssd to use the same files from nss-altfiles 3. start sssd 4. selinux denial Actual results: grep avc /var/log/audit/audit.log |grep sssd_be | audit2why type=AVC msg=audit(1678211275.874:251916): avc: denied { watch } for pid=982783 comm="sssd_be" path="/usr/lib" dev="dm-0" ino=33554564 scontext=system_u:system_r:sssd_t:s0 tcontext=system_u:object_r:lib_t:s0 tclass=dir permissive=0 Was caused by: Missing type enforcement (TE) allow rule.

You can use audit2allow to generate a loadable module to allow this access. Expected results: Permit watch on system_u:object_r:lib_t:s0 Additional info: SSSD folks suggest using nss-altfiles as a proxy source. For folks looking to test this and perform a phased migration this policy tweak seems necessary.
