We are considering migrating our Novell eDirectory on-premise directory to AAD DS. One thing that we use our current directory for is storing SSH public keys for users, which are in turn used to allow users to log in to Linux instances.
I have seen documentation that states that AAD DS does not allow extending the LDAP schema (including adding User object attributes), but I cannot find documentation stating what the default schema looks like.
Is it possible to store users' public keys for SSH in AAD DS? Where can I see the documentation for the default schema (I'd like to know what I'm buying before I dive in)?
