Rebuilding my 2400's system here. I did a fresh 8.6 install. Installed the CarbonLib 1.6 and all the files extracted from Airport 2.0.4's Tome. While Airport seems to work fine, the "Airport Admin Utility" won't launch. It complains "can not find KeyChainLib". I copied over the three KeyChain related files from my 9.1 partition into the System Folder. Downloaded the Keychain SDK 1.0.1 and put the "KeyChainLib" file from there in the Extensions folder. Same error. The Developer documentation mentioned a file called "KeyChain Library". Does anyone here has such a file? Anyone here running 8.6 with Lucent Cards? Thanks. jake
