Hello Yoann. I am working with similar issues at the moment in a biotech company in Denmark.
First of all what authentication setup are you using?
If you are using sssd there is a very simple and useful utility called sss_override
You can óverride' the uid which you get from LDAP with the genuine one.
Oops. On reading your email more closely.
Why not just add ceph to your /etc/group file?

Hello,
I'm facing an issue with ceph's UID/GID 65045 on an LDAPized server, I have to install ceph-common to mount a cephfs filesystem but ceph-common
fails because a user with uid 65045 already exist with a group also set at 65045.
Server under Ubuntu 16.04.4 LTS

The user is correctly created but the group not.

Is there a workaround for that?
