Roundcube doesn't work when password contains escape character "\"

[cheungpat]

If the password contains a escape character "\", Roundcube does not allow me to login and display the "Login failed." message. The error log entry was,

[13-Jul-2006 01:39:12 +0800] IMAP Error: Authentication failed (LOGIN):<br>"a001 NO Login failed." in on line

After changing the password to something without the escape character, Roundcube works again.

It doesn't even accept dieresises (german "umlauts") like "ä" "ö" "ü"

I was able to reproduce this using a test account with a password of "test\2" - However if I escape it in the password box, i.e. "test
2" then it proceeds to login successfully. I suppose the underlying question is whether or not you should be allowed to enter escape characters in the password field, or whether '\' should always be treated as only a '\' and never as a special character.

In my environment the IMAP server is Courier and it uses my UNIX password. I don't have any problem with my password except logging into Roundcube. I also have SquirrelMail? and it doesn't have problem accepting the single escape character.

I think if some IMAP server treats '\' literally, Roundcube should correctly handle this.

IMAP specification ​http://www.ietf.org/rfc/rfc2060.txt,

From RPC:

• password ::= astring
• astring ::= atom / string
• atom - An atom consists of one or more non-special characters.

RC should use quoted format - escaped specials enclosed in double quotes.
