This patch checks if the relevant functionality is actually available before using it for authentication: 1. check if function imap_open() exists before using it 2. check if smbclient executable exists during smb auth 3. check if ftp/ftps stream wrappers are registered before using them for auth This fixes a crash (white page) that happens when using IMAP authentication and the IMAP extension is not installed.
