      Eduardo,
Can you confirm this was with a fresh CVS checkout of RE24, and not with 
2.4.7?
Thanks,
Quanah

Hi Quanah, I have followed your instructions. As you can check the slapd
binary is not stripped:
-bash-3.00# file slapd
slapd:          ELF 32-bit MSB executable SPARC Version 1, dynamically
linked, not stripped
The backtrace of the slapd process is the following:
<<< dnPretty: <cn=Eduardo Izaguirre

Hi all, we are using Openldap as a metadirectory against a couple of
AD servers. The slapd server core dumps when a request of all
attributes of one entry is issued. This is the output of the slapd
server using the debug level -1:
Hi Eduardo,
Please test with the current CVS of REL_ENG_2_4.  Please build without
optimization, and with debugging symbols.  Make sure you don't strip
slapd on install.  If you can repeat this with current CVS, please
provide a gdb backtrace of the non-optimized, non-stripped slapd.
Thanks,
Quanah
