Platform: SAMBA_3 CVS (8:00 GMT, 05/26) in Debian 3.0 (2.4.18, gcc
version egcs-2.92.11)UltraSparc IIi. openldap libs (openldap 2.0.27).
 
  ./configure --with-ldapsam
  passdb backend = ldapsam:<url>

The Samba reports internal-panic errors when some windows action is performed
like: enum shares, mount a volume, always about get_ntlm_challenge calls, but
reports stack errors, someone related to ldap.

The bin/smbpasswd -a -m <machine> runs well. In all cases, the ldap also
responds well.

I found these errors at level5 and 10:
