Facing error while creating OAuth Adaptor for PDO

[sanjivsharmalv]

Facing the error : “Invalid DSN”, please advise what is wrong with DSN:

[makxk]

Try beginning the DSN with sqlite:// (double slashes instead of single slashes)?
Apparently, the path has to look like so on linux:

sqlite:////full/unix/path/to/file.db

and like so on windows

sqlite:///c:/full/windows/path/to/file.db?mode=0666

Hope that helps
