(ITS#6303) Buffer overflow with new glibc

Full_Name: Jan Zeleny Version: 2.4.18 OS: Fedora 12 URL: http://jzeleny.fedorapeople.org/patches/openldap/openldap-2.4.18-ldif-buf-ov... Submission from: (NULL) (62.40.79.66)

I tried to make configuration directory (instead of config file) work in Fedora 12. I noticed that new builds of slapd fail during start with config dir. The start results in SIGABRT, backtrace and buffer overflow error. I traced the bug to ldif.c. I guess new version of glibc has some kind of mechanism which is checking boundaries of structures and isn't allowing write out of those boundaries. I made attached patch to avoid the issue. After testing it seems to be working well.
