VPN and Domain Authentication

I have a weird problem.

I configured a SSL VPN for LDAP users, using my ldap local server.

At ldap configurtion, at Common Name Identifier, i set sAMAcountName so users have to use their windows logon name to login to vpn portal.

I have a domain account with name "Test" and logon name "Test"

When i use SSLVPN web mode and i set username: "Test" and my password i can succesfully login.

After login lets say i create a bookmark named "mybookmark" and logout.

If i try to login with username: "test" (lower t) and same password i can succesfully login but no bookmark is shown. Seems like a different account.

At my ldap there is no "test" user. The only user exists is "Test"
