I have a webserver running sarge. I'm building a replacement using etch.
It's not an upgrade, it's a fresh install. So, everything is different.

The bug is simple enough to replicate: Just create a password entry
containing non-ascii in the gecos such as in the example I gave, set
"passwd: nis" in /etc/nsswitch.conf and then try to login.


An additional note:

I created two test entries in my Solaris auto_common map
(used by my auto_master on Solaris, but that isn't relevant).
One with the key containing non-ascii, one where the value did.

When I used ypcat to retrieve the map, both entries were present
on Solaris 10 and debian nis 3.13-2.

However with nis 3.17-6, the non-ascii key was not found at all
and the non-ascii value was corrupted, containing part of another
map entry instead of the expected content:

    sol-10$ ypcat -k auto_common|grep test|od -c
    0000000   t   e   s   t   2 367   m       w   i   b   b   l   e   :   /
    0000020   p   a   t   h   2  \n   t   e   s   t   1       w   i   b   b
    0000040   l   e   :   /   p   a   t   h   1 367   m  \n
    0000054

    nis_3.13-2$ ypcat -k auto_common|grep test|od -c
    0000000   t   e   s   t   2 367   m       w   i   b   b   l   e   :   /
    0000020   p   a   t   h   2  \n   t   e   s   t   1       w   i   b   b
    0000040   l   e   :   /   p   a   t   h   1 367   m  \n
    0000054

    nis_3.17-6$ ypcat -k auto_common|grep test|od -c
    0000000   t   e   s   t   1       m   a   p   l   e       e   d   g   e
    0000020   :   /   e   x   p   o   r   t   /   p   k   g   /   m   a   p
    0000040   l   e   /   9   .   5  \n
    0000047
