Description mreynolds 2018-07-10 12:43:35 UTC

Description of problem:

We can not use cracklib dictionary checking in our aplication (389-ds-base and freeipa) because selinux blocks access to the cracklib dictionary files.  This was supposed to be fixed in RHEL 6, but it's a problem on RHEL and Fedora 28.

BZ - 1175188 - selinux blocks slapd access to cracklib

I tested with:

selinux-policy-3.14.1-32.fc28.noarch
libselinux-2.8-1.fc28.x86_64

Comment 2 Milos Malik 2018-07-10 12:48:43 UTC

Please collect SELinux denials triggered by your scenario:

# ausearch -m avc -m user_avc -m selinux_err -m user_selinux_err -i -ts today

and attach them here.

Comment 3 mreynolds 2018-07-10 13:06:51 UTC

Here it is (thanks!):


[root@localhost password]# ausearch -m avc -m user_avc -m selinux_err -m user_selinux_err -i -ts today
