Oracle context and MS Active Directory

Question

Hello,
I have one pc with Windows Server 2003 and Oracle 10g r2
When I add a user from my Active Directory in the External OS Users of the Oracle Managed Object (via mmc), I get this error:
ORA-30041: Cannot grant quota on the tablespace
And when I try to connect with this user (Active Directory user) to isqlplus, I get another error:
ORA-28030: Server encountered problems accessing LDAP directory servic
Someone know how to resolve these errors ?
Server's Configs
Active directory name: cyclops.home.com
Host name: server.cyclops.home.com
My database name in the Oracle context object of my Active directory: oracle_db

When I use this cmd ldapbind -h cyclops.home.com that works.
If I log to isqlplus with the system user and do select username from all_users; I can see my Active Directory user.
I also changed the LDAP_DIRECTORY_ACCESS parameter to PASSWORD (default was SSL) but that changed nothing.
Maybe the problem is from the Oracle wallet, I did one when I have created the database but I don't know well about it and the use. I think I should have something in my sqlnet.ora file related to the wallet but I don't know how to set.
I search on internet, some homepages said I should use Oracle Net Manager to set the wallet location but I found nothing in Oracle Net manager for it.
