The example shows how to verify an unmapped user's authentication and authorization properties using LDAP from a given IP address. Run:
tdgssauth -u drct01 -m ldap -i 198.51.100.20
The user's name (-u) is the same as it is specified in a bteq .logon command. The -m option specifies the logon mechanism to use (LDAP in this case). The -i option specifies the IP address from which the user will connect.

The following explains the output from the command:
|1> Enter a password||When prompted, enter the user's password for the specified mechanism. In this example, enter the user's LDAP password because the specified mechanism is ldap. If KRB5 is the specified mechanism, enter the user's KRB5 password.
Use -w and specify the user's password on the command line to avoid being prompted for the password.
It is not recommended to specify the user's password on the command line.
|2> Status: authenticated, authorized||The user authenticated and authorized successfully.|
|3> Database user: drct01 [unmapped user, autoprovisioning candidate]||The user is not mapped to a Teradata database user (an unmapped user) and this user is a candidate for autoprovisioning.|
|4> Profile: profxu1||The user has the profxu1 profile associated with the session.|
|5> External roles: extrole01xu1, extrole02xu1, extrole03xu1||The user is permitted to occupy the three external roles, extrol01xu1, extrole02xu1, and extrole03xu1. The DBA must create those roles in the database and grant them rights.|
|6 > Authenticated user: ldap://dsa1.example.com:389/uid=drct01,ou=principals,dc=example,dc=com||The identity of the user in the directory server and the server that authenticated the user.|
|7> Audit trail identifier: drct01||The user's audit trail identifier used in event logs caused by a session logged on as this user.|
|8> Authenticating service: dbssvc||The service name of the service used to authenticate the user. The service is configured in the <LdapConfig> section of the TdgssUserConfigFile.xml file.|
|9> Actual mechanism employed: ldap [OID 18.104.22.168.22.214.171.124.1012.1.20]||The name and Object Identifier (OID) of the actual authentication mechanism used to authenticate the user. Note, the TDNEGO mechanism reports the actual mechanism that it selected to authenticate the user. Other explicitly named mechanisms report themselves here.|
|10> Mechanism specific data: drct01||The mechanism specific data. This data is used by other parts of the system during the login process and is not used by TDGSS. In most, if not all cases, this simply provides the name of the user from the -u command line option.|
|12 - 17> Security context capabilities: replay detection, out of sequence detection ... exportable security context||These lines tell us what a particular security context provides. The security context is the one established for the named user using the specified mechanism.|
|19> Minimum quality of protection: None||The minimum QoP that the user is required to use for the life of the session. In this example, during the life of a session this user can use any QoP including no QoP at all.|
|20> Options: none||The connection options in effect for this user. In this case, the word none indicates that this is a normal connection. This value may contain has-policy or no-direct-connect. has-policy says that the user must use only a plaintext connection to the database and is used for very specialized purposes. no-direct-connect says that the user is not permitted to connect directly to the database, but must instead come through Unity.|
