[Samba] ldap crashes right after samba updates password

[Luís Miguel Silva]

Hello all,

This week i successfully managed to create a openldap server/domain using
openldap and samba 3.0.11.

Alltough everything is working correctly, when i change the password on the
server via the "smbpasswd" command (the one which comes by default with samba)
or by a windows machine, my openldap crashes.

Here is a output of a debug session of openldap:

Segmentation fault

I was trying to set "xpto" as my password.

The "funny" thing is that:
a) the password gets changed all the same (allthough slapd crashes)
b) i can change the password without any problem via the smbldap-passwd (from
idealx).

Can anybody help me with this?

Im using trustix 2.2 with:
root at ad /# rpm -qa | grep samba
samba-common-3.0.11-2tr
samba-3.0.11-2tr
samba-client-3.0.11-2tr
root at ad /# rpm -qa | grep ldap
openldap-2.1.30-2tr
openldap-libs-2.1.30-2tr
nss_ldap-220-1tr
openldap-devel-2.1.30-2tr
ldapclients-common-175-1tr
openldap-servers-2.1.30-2tr
openldap-utils-2.1.30-2tr
root at ad /#

PS: does anybody know of a administration interface which as the hability to
encode the sambaLMPassword and the sambaNTPassword directly onto openldap?

Thanks in advance,
