Re: ber_get_next: Assertion failed

[Guy Roussin <guy.roussin@teledetection.fr>]

Thank you Howard and Pierangelo for your very quick answers,

But this server is in production. I can't make lot of test on it.

I notice than there is 2 packages in Debian Sarge (don't know why,
but libldap-2.2-7 depends on libldap2) and 2 libldap_r (see dpkg -L).
It seems not so easy to change/test a new version on this
samba pdc server.

What do you think ?

Thank you.

Guy Roussin
