I'm setting up a new sambserver, migrating from 2.2.8a with ldap backend to 3.0.x (3.0.2a and 3.0.3pre2 tested) with openldap 2.1.26 backend and using sambaSamAccount
I'm experiencing the following problem:
- Roaming profiles sometimes work, sometimes not (most of the time not) and show erratic behaviour like removing the local copy (without having the DeleteRoamingCache key in my registry) on a windows XP with SP1 joined to the domain
I think I've pinpointed the problem to NT MD4 password checking (libsmb/ntlm_check.c:ntlm_password_check(322))
With debug on 100 and DEBUG_PASSWORD on it shows the following:

It does that 3 times correctly, I guess it checks the authentication when the user logs on. Now a minute later it checks again, I guess for connecting to the profiles share? but now it fails. What results in Windows XP telling me that it can't find the profiles directory.

When I edit libsmb/ntlm_check.c to always return a NT_STATUS_OK instead of a NT_STATUS_WRONG_PASSWORD the last check ofcourse works and the roaming profiles work perfectly. (but that isn't very secure ;)
This is my current config, but I've used various mutations of it without success ;)
Please let me know if you need any more information. Thanks,
