So, there are two related concepts here:
- Authentication: Establishing the identity of the client
- Authorization: Specifying what the authenticated client is allowed to do.
ALLOW_READ / ALLOW_WRITE specifies an authorization. Once the client has been authenticated, these are applied.
>From the message you receive, it appears that there is a failure in authentication: it looks like it has tried GSI, KERBEROS, and FS.
If you just want host-based authentication, you probably want to enable the CLAIMTOBE mode: that allows the client to simply assert an identity, and the server will believe it.
Likely, this means adding the following to the server config:
SEC_DEFAULT_AUTHENTICATION_METHODS = CLAIMTOBE, $(SEC_DEFAULT_AUTHENTICATION_METHODS)
And this to the client config:
SEC_CLIENT_AUTHENTICATION_METHODS = CLAIMTOBE, $(SEC_CLIENT_AUTHENTICATION_METHODS)
Hereâs some further reading on the security configuration:
Of course, for systems not on dedicated networks, CLAIMTOBE is fairly weak. Further, even on dedicated networks, having stronger authentication methods is part of a good defense-in-depth strategy.
Hope this helps!
