Isn't there any standard for numbering GIDS?

Hi.

I'm currently installing an LDAP server on a Debian Virtual Environment that is hosted on a physical Gentoo server with OpenVZ. I was about to run the migration scripts and import various stuff to the directory when I realized not all group IDs were mapped to the same names between Debian and gentoo, for instance.

Example: in Debian daemon and bin accounts map to 1 and 2 respectively, while 1 and 2 under Gentoo are bin and daemon respectively -- i.e. reversed. Also groups cdrom, games and usb don't have the same IDs between both distributions.

This basiacally means that I can't trust group ID's if I want to be able to use then on different distributions from a centralized user management system like LDAP. Given that different distributions have different IDs for these groups I can't safely use them to grant these accounts local access to the CDROM or USB devices, for instance, right?

Is there any solution or workaround for that issue?

Till now only the users group has an ID of 100 in both Debian and Gentoo. But it might as well be different on other distributions, right?

Thanks in advance.

Thanks for your lights, aceFruchtsaft.

So it basically means that Padl MigrationTools scripts are mostly useless (at least for groups and users, which ID < 1000) since they might map things that don't have the same IDs on different distributions, right? In other terms, they would make sense only if the operating system holding the LDAP server *and* the one on workstations are exactly the same one distribution, am I right?
