Samba as supported in Spectrum Scale uses the "autorid" module for creating internal id mappings (see man idmap_autorid for some details).
Officially supported are also methods to retrieve id mappings from an external server: https://www.ibm.com/support/knowledgecenter/en/STXKQY_4.2.1/com.ibm.spectrum.scale.v4r21.doc/bl1adm_adfofile.htm The earlier email states that they have a " .tdb backend for id mapping on their current server. ". How exactly is that configured in Samba? Which Samba version is used here? So the plan is to upgrade the cluster, and then switch to the Samba version provided with CES? Should the same id mappings be used?

We have upgraded their 2nd node to 4.2 and have successfully tested joining the domain, created smb shares, and validated their ability to access and control permissions on those shares. They are using .tdb backend for id mapping on their current server. I'm looking to discuss with someone the best method of migrating those tdb databases to the second server, or understand how Spectrum Scale does id mapping and where it stores that information. Any hints would be greatly appreciated.
