A debug file does not get created until a module writes to it. Therefore, in the default error mode no debug files may be generated. The debug files that get created on a basic login with the debug level set to message include:
amAuth
amAuthConfig
amAuthContextLocal
amAuthLDAP
amCallback
amClientDetection
amConsole
amFileLookup
amJSS
amLog
amLoginModule
amLoginViewBean
amNaming
amProfile
amSDK
amSSOProvider
amSessionEncodeURL
amThreadManager
The most often used files are the amSDK, amProfile and all files pertaining to authentication. The information captured includes the date, time and message type (Error, Warning, Message).
