UserIdentityTokens
OPC UA specifies a set of UserIdentityTokens to provide different methods of authentication. The CompactCom module only supports the UserNameIdentityToken. Access will be granted to user accounts assigned to roles that are configured to have OPC UA access, see Configuration.
The Anybus CompactCom supports the UserIdentityTokens listed in the table below.
PolicyId | UserTokenType | SecurityPolicy |
|---|---|---|
Username_Null | UserName | SecurityPolicy specified to NULL will make the UserIdentityToken to inherit the SecurityPolicy of the endpoint. |
Username_None | UserName | SecurityPolicy None |
Username_Basic256Sha256 | UserName | SecurityPolicy [B] – Basic256Sha256 |
Username_Aes128_Sha256_RsaOaep | UserName | SecurityPolicy [A] – Aes128-Sha256-RsaOaep |
Which UserIdentityTokens that are enabled on an endpoint depends on the security mechanisms that the endpoint uses.
