unable to logon using LDAP mechanism

I'm trying to setup teradata with LDAP (sun one) authentication (not authorization)

I get this error when trying to logon using BTEQ :

.logmech ldap
Teradata BTEQ 08.02.03.03 for WIN32. Enter your logon or BTEQ command:
.logon demotdat/auto101

.logon demotdat/auto101
Password:
*** CLI error: CLI2: BADLOGMECH(507): Requested logon mechanism is not available.

Using tdsbind works :

C:\Program Files\NCR\Teradata GSS\nt-i386\12.00.00.00\bin>tdsbind.exe -u auto101

Enter LDAP password:
LdapGroupBaseFQDN: dc=XXXXXX,dc=com
LdapUserBaseFQDN: dc=XXXXXX,dc=com
LdapSystemFQDN:
LdapServerName: hostnameABC
LdapServerPort: 7585
LdapServerRealm: hostnameABC.XXXXXX.com

FQDN: uid=auto101,ou=people,dc=XXXXXX,dc=com
GUID: 00000000-0000-0000-0000-000000000000
Audit trail ID: AAAAAAAAAAAAAAAAAAAAAAAAAAA

Anyone know how I can troubleshoot this ???
Thanks,
Marc
