mod_sasl2_fast: Fix harmless off-by-one error (invalidates existing tokens!)
Problem:
This was causing the key to become "<token>--cur" instead of the expected
"<token>-cur". As the same key was used by the code to both set and get, it
still worked.
Rationale for change:
Although it worked, it's unintended, inconsistent and messy. It increases the
chances of future bugs due to the unexpected format.
Side-effects of change:
Existing '--cur' entries will not be checked after this change, and therefore
existing FAST clients will fail to authenticate until they attempt password
auth and obtain a new FAST token.
Existing '--cur' entries in storage will not be cleaned up by this commit, but
this is considered a minor issue, and okay for the relatively few FAST
deployments.

--- labels: - 'Stage-Alpha' summary: 'XEP-0273: Stanza Interception and Filtering Technology' ... Introduction ============ [SIFT][XEP-0273] is a technology to allow clients to filter incoming traffic on the server. This helps save bandwidth, etc. Compatibility ============= ----- ------- 0.7 Works ----- ------- Quirks ====== This implementation is a work in progress. - Stanzas to full JIDs get sifted correctly - Stanzas to bare JIDs are currently allowed/disallowed for all resources as a whole, and not for individual resources - Presence is only sent to available resources, and probes are not sent for unavailable reasources - This module currently does not interact with offline messages (filtered messages are dropped with an error reply) - Not tested with privacy lists
