[Bug 31675] Re: Problem when making many users with "users admin. tool" at one time

[Gary Coady]

I think these are both the same problem.

Creating a large number of users causes an invalid XML file to be sent to the backend - a line is truncated at 4096 characters, so it looks like a static buffer is filled.

The backend tools don't use a "real" XML parser, so they will try to use an invalid XML document. The corrupted file causes users not to be added, groups to be deleted, etc.

In my case, it deleted the groups: adm, tty, disk, kmem, dialout, fax, voice, cdrom, floppy, tape, sudo, audio, dip, operator, src, shadow, utmp, video, sasl, plugdev, staff, users, crontab, ssh, slocate, scanner and admin.
