> Project: Qpid Proton
> Issue Type: Bug
> Components: proton-c
> Affects Versions: 0.10
> Reporter: Gordon Sim
> Assignee: Andrew Stitcher
>
> E.g. if a broker sends a sasl-mechanisms frame with a single symbol as the
> value of the mechanisms field, then it appears that the cyrus-sasl support in
> proton-c doesn't recognise that offered mechanism(?)

> [0x2605d80]: <- SASL
> [0x2605d80]:0 <- @sasl-mechanisms(64) [sasl-server-mechanisms=:ANONYMOUS]
> [0x2605d80]:sasl error: SASL(-4): no mechanism available: No worthy mechs

> From the spec, section 1.4:
> {quote}
> The multiple attribute of a field description controls whether multiple
> element values are permitted in the representation. A single element of the
> type specified in the field description is always permitted. Multiple values
> are represented by the use of an array where the type of the elements in the
> array is the type defined in the field definition.
