mamba: Resolving from cache fails when cache dir rights are applied with ACL's

OS : RHEL7 Mamba version : 0.15.2 Conda version : 4.10.3

How to replicate :

Create cache dir

mkdir -p /tmp/cache/conda

Add ACL’s for your user

 setfacl -m d:u:<user>:rwx /tmp/cache/conda/
 setfacl -m u:<user>:rwx /tmp/cache/conda/

Change folder owner to root to rely solely on ACL’s

chown root:root /tmp/cache/conda/

Expected behavior

conda create -n test python The command works fine and the cache is populated with downloaded packages.

Actual behavior

mamba create -n test python Resolving breaks while accessing cache registry

RuntimeError: Operation not permitted: '/tmp/cache/conda/cache/f7c32d1b.json'

In our use case, package cache has to be accesible to mutiple groups. We cannot rely solely on user:group rights.
