OpenLDAP is potentially a component of an IAM system, but it's not really something you'd use ‘to sign in to Google Cloud’. OpenLDAP is a server which implements the LDAP query protocol. As such, it maintains a directory of users (and other things) and attributes related to them (such as usernames). It also contains client libraries which allow you to use LDAP to query suitable servers, from the command-line or from a program. LDAP is a protocol, which you might use to query a server which implements that interface. The Wikipedia page on OpenLDAP [1] includes links to the openldap.org site, to further information about LDAP, and to associated software such as SASL. I don't know anything about Google Cloud. Azure has its own (intricate!) permissions system which is based on Active Directory. To use that, you'd want to study the Azure documentation. Note that Active Directory implements an LDAP interface, and shares much of the LDAP data model, though I don't know much about how deeply the interoperability _really_ goes. A local LDAP directory (eg, one using OpenLDAP) may work in consort with a separate IAM system such as the ones you mention, but that's starting to get intricate, and wouldn't be one of the core use-cases. Good luck with your research. Best wishes, Norman [1] https://en.wikipedia.org/wiki/OpenLDAP -- Norman Gray : https://nxg.me.uk
