Description alex 2012-05-07 16:21:35 UTC 
Overview:
"net join -d10 -U admuser" in ADS mode dumps core in ads_try_connect

Solaris 10u10 / MIT krb5-1.10.1 / openLDAP-2.4.30 / bdb-5.1.29


Steps to Reproduce:

Compile and install samba using the following options :
./configure --with-ads  --with-ldap=/usr/product/openldap-2.4.30 --with-krb5=/usr/product/krb5-1.10.1 --with-included-popt

Use the following smb.conf :

[global]
        realm=CIB.NET
        workgroup=CIB.NET
        security=ADS
        encrypt passwords = yes
        bind interfaces only = true
        interfaces = msusersncs
        netbios name = msusersncs
        msdfs root = yes
<removed log, lock dir, shares, etc..>

run "net join -d10 -U admuser"

Additionnal info :
Same results whether I use SunStudio compiler, or gcc
