I am no samba expert. Reading your email produce 2 thots.
1. If I have not read wrongly, you DID NOT managed to reproduce my scenario cos when you joined Domain A , login as user of DomB , you got the expected result, the Domain B's sambahomepath and drive gets map to the user B. Mine result was this:
I joined Domain A, login as user of Dom B, I did NOT get Domain B's sambahomepath and drive for the specific user of Dom B.
I am mentioning this cos you said "I've tried to reproduce your problem and was surprised to see that I've got your expected behavior."
2. If you managed to map wherever you joined, GREAT. That means I've got hope. Got I wanted to give up on samba already. Do you believe I tried 2 days just to troubleshoot this problem?????
I do not know what logs you want. Maybe you can specify for me. Anyway i get call you? I am anxious to get the domain running. I do not know how to paste as well cos it is very long.
My ldap settings may be weird. I got the same tree for my ldap settings. the main suffix is dc=uwcsea,dc=org. Then the DomA is ou=staffnet,dc=uwcsea,dc=org. Dom B is ou=studentnet,dc=uwcsea,dc=org. All the domain controllers are replica of the main LDAP server which is running version 2.0 of OpenLDAP. (DEBIAN).
On my libnssldap.conf, pam_ldap.conf and ldap.conf are using base=dc=uwcsea,dc=org cos I need to see both sides of the domain right? Getent passwd works. But some other stuff may not work as expected. The main thing is that logging in as users of both domains are fine.
BTW, I do not have uid=root. One side is uid=Administrator and the other uid=stuadmin. All their uids are 0.
I noted that uid=root is very required to do "net rpc trustdom list". Anyway my brains are stuffed.
Thanks for the glimpse of hope. Please give suggestions as I really need them. THANKS a lot for testing out on your side.
