Hi, I am using FreeRADIUS 3.0.27 on EL9, and I'm trying to set a Vendor Attribute in replies. For context, I am trying to authenticate SuperMicro BMCs with LDAP (see thread https://lists.freeradius.org/pipermail/freeradius-users/2018-March/091085.ht...) So in my enabled site I edited the post-auth section post-auth { update { reply:Attr-26 := "0x483D342C20493D34" } } This results in "Cannot parse RHS hex as the data type of the attribute Vendor-Specific" As it's missing Vendor ID, I tried to add it. Super Micro PEN on IANA is 10876, so full vendor attribute should be 1A1200002A7C483D342C20493D34 if I am correct: post-auth { update { reply:Attr-26 := "1A1200002A7C483D342C20493D34" } } And here the result is Must use 'Attr-26 = ...' instead of 'Vendor-Specific = ...' , even if I am setting reply:Attr-26 Does anyone have a suggestion? I'd like to add it to post-auth (and not to mods-enabled/ldap) to then add a conditional on NAS-Identifier = "SUPERMICRO BMC" Thanks in advance Francesco -- Francesco Di Nucci System Administrator Compute & Networking Service, INFN Naples Email: francesco.dinucci@na.infn.it
