credentials mount cifs - dot in password string

Question

I'm trying to use files from Windows box in Linux.

If I use mount -t cifs username=xyz, password=Abc.DF,... ==> mount success

If I put a line in /etc/fstab

//Windows/share/c /WinShare username=xyz,password=Abc.DF,.... ==> mount success

When putting credentials parameter in /etc/fstab

//Windows/share/c /WinShare credentials=/root/.passwdfile .....

/root/.passwdfile has two lines :

username=xyz
password=Abc.DF

got

**mount error 13 = Permission denied**

putting Quotation marks around password=Abc.DF

after

mount /WinShare

got prompt

Password :

and by typing Abc.DF ==> success

Security policy in Windows box is requiring dot(.) in pasword string.

Any Idea ???

Answer 1

You cannot use the credentials file for passwords containing special characters like "." or ",".

Note that a password which contains the delimiter character (i.e. a comma ',') will fail to be parsed correctly on the command line. However, the same password defined in the PASSWD environment variable or via a credentials file (see below) will be read correctly.

Source: Manpage mount(8)

A solution would be to set up an environment variable for this share. The mount command will use this password and special characters are allowed.

I haven't read of escaping special characters in the credentials file.

I found a bug entry for your issue, propably, you would like to participate or get notified:
Cannot mount CIFS share if password contains non-ASCII character

There are several posts on the mailing list about this topic: List linux-cifs-client "password credentials file"

0	guerda's answer is quoting text that says the exact opposite. It should be okay to have special characters in the credentials file, it is on the command line that they cannot be parsed. link answered 09 Dec '10, 11:05 unwind 1 accept rate: 0%
