[Samba] Security context stack overflow on Debian5+LDAP
Hi I'm setting up a Samba PDC, with auth over Zimbra's LDAP, with this howto: http://wiki.zimbra.com/index.php?title=UNIX_and_Windows_Accounts_in_Zimbra_LDAP_and_Zimbra_Admin_UI_6.0 System is a fully updated Debian 5. All packages from distro. Samba is 3.2.5-4lenny6. Now everything is almost ok, but I'm getting an error when trying to mount the samba share: [2009/09/10 09:44:07, 2] passdb/pdb_ldap.c:init_group_from_ldap(2344) init_group_from_ldap: Entry found for group: 10001 [2009/09/10 09:44:07, 0] smbd/sec_ctx.c:push_sec_ctx(210) Security context stack overflow!

Hmmm. 3.2.5-4lenny6, is that an up-to-date package? I'm pretty certain I have seen that ages ago and it was fixed. Is it possible for you to retry with 3.4.1? If not, the least we need is a debug level 10 log leading up to this, and if possible also a network trace of the LDAP traffic.
