Bug#452504: pam_mount.conf conversion fails for group names with blanks

>converting the plain-text pam-mount.conf to the new XML format
>(why, oh why)

why -> throwing out BSD-era code and instead use established 
libraries. libxml2 is installed anyway as a dependency of many programs.
(`rpm -e libxml2 2>&1 | wc -l` alone gives 135 lines on a
casual user (kde/gnome in all colors) desktop.)

Bug#452504: pam_mount.conf conversion fails for group names with blanks

[Raphael Wimmer]

Package: libpam-mount
Version: 0.29-2
Severity: serious

When converting the plain-text pam-mount.conf to the new XML format (why,  
oh why), user names in single quotes get truncated, leading to a wrong and  
invalid XML file. pam_mount checks if the XML config file is valid. Thus,  
if pam_mount is a required module, no login is possible anymore.
Maybe the bug is fixed in 0.29-3, however, the broken XML file is not  
fixed when upgrading to 0.29-3.


The effect for me: the pam_mount stanza

volume '@medieninformatik studenten' cifs aga.medea H_Students  
/home/&/_HOME - - -


gets converted to

path="H_Students" server="aga.medea" fstype="cifs" />


Please note the chopped off group name and the single quotation mark. This  
quotation mark obviously makes the file invalid (the cause for this stupid  
group name is Microsoft's Active Directory, which we authenticate against  
using winbind).
Additionally, for groups the conversion should remove the '@' and change  
the attribute name to 'prgp'.

The correct conversion would be:

path="H_Students" server="aga.medea" fstype="cifs" />



Cheers,
Raphael
