OAuth2 vs OpenLDAP: What are the differences?
Developers describe OAuth2 as "An open standard for access delegation". It is an authorization framework that enables a third-party application to obtain limited access to an HTTP service, either on behalf of a resource owner by orchestrating an approval interaction between the resource owner and the HTTP service, or by allowing the third-party application to obtain access on its own behalf. On the other hand, OpenLDAP is detailed as "An open source implementation of the Lightweight Directory Access Protocol". It is a free, open-source implementation of the Lightweight Directory Access Protocol. Lightweight Directory Access is an application protocol that is used to crosscheck information on the server end.
OAuth2 and OpenLDAP can be primarily classified as "User Management and Authentication" tools.
According to the StackShare community, OAuth2 has a broader approval, being mentioned in 22 company stacks & 38 developers stacks; compared to OpenLDAP, which is listed in 13 company stacks and 21 developer stacks.
