Permission Error when using different keyring in connect-external-ceph command

[mateofloreza]

Hi all,

I'm currently working on integrating the rook-ceph addon and connecting my external charmed ceph with my microk8s cluster. One of my requirements is to use a specific osd pool, and I've created a user with the defined permissions. However, I'm facing an issue when using the following command:

sudo microk8s connect-external-ceph --ceph-conf ceph.conf --keyring ceph.keyring --rbd-pool ericsson_pool

If the ceph.keyring is different from the client.admin keyring, I'm unable to connect to my external ceph, and I'm encountering a rados.PermissionError. However, if I use the client.admin keyring, it works as expected.

I've included the error output below for reference:
