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"
That's a double quoted string. The "0x" text is part of the string.
This results in "Cannot parse RHS hex as the data type of the attribute Vendor-Specific"
Exactly it can't parse it as hex, because it's not hex. It's a double quoted string.
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"
Drop the quotes. Use: reply:Attr-26 := 0x1A1200002A7C483D342C20493D34 The server has tests for this, so it should work. Alan DeKok.
