getent group with openldap backend crashes ## 3rd

[Steffen Kolbe <kahla_kolbe@web.de>]

Hi Kurt and all others,

Do you have some better / more ideas for retrieving more special 
debugging informations?

Can you explain please how / where the data of the queries is stored?

I've tested this also under 32bit (suse9.3 + Fedora4) official binaries 
and the result was the same error. So I'm not sure that origin is in 
another binary.

I try to understand the code, but for a "non LDAP developer" like me it 
isn't easy...


I have to solve this problem or all users (~500+) have to work with 
Windows in the future and for all times ;-)


thanks for your efforts and best regards

Steffen

An executable which links in (directly or indirectly)
both libldap and libldap_r is broken.  Seems to be the
case here.
