This example shows how to verify a mapped user’s properties using LDAP from a given IP address. Run:
tdgssauth -u diperm01 -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.
Result:
1> Please enter a password: 2> Status: authenticated, not authorized 3> Database user: perm01 [permanent user] 4> Profile: profperm01 5> External roles: extrole01perm01, extrole02perm01, extrole03perm01 6> Authenticated user: ldap://example.com:389/CN=diperm01,OU=people,DC=example,dc=com 7> Audit trail identifier: diperm01 8> Actual mechanism employed: ldap [OID 1.3.6.1.4.1.191.1.1012.1.20] 9> Mechanism specific data: diperm01 10> 11> Security context capabilities: replay detection 12> out of sequence detection 13> confidentiality 14> integrity 15> protection ready 16> exportable security context 17> 18> Minimum quality of protection: none 19> Options: none
In this example, we see that the directory user diperm01 maps to the permanent Vantage user perm01 on line 3.
The following explains the output from the command:
| Line Number | Description |
|---|---|
| 1> Please enter a password | When prompted, enter the user's password for the specified mechanism. In this example, the user's LDAP password is entered because the specified mechanism is LDAP. If KRB5 is the specified mechanism, enter the user's KRB5 password. It is not recommended to specify the user's password with -w on the command line.
|
| 2> Status: authenticated, not authorized | The user authenticated successfully and is not unmapped to a Teradata object. |
| 3> Database user: perm01 [permanent user] | The database user to which the directory user is mapped. Notice that the directory user, diperm01, maps to the permanent database user, perm01. |
| 4> Profile: profperm01 | The user has the profperm01 profile associated with the session. |
| 5> External roles: extrole01perm01, extrole02perm01, extrole03perm01 | The user is permitted to occupy the three external roles, extrole01perm01, extrole02perm01, and extrole03perm01. The DBA must create those roles in the database and grant them rights. |
| 6 > Authenticated user: ldap://example.com:389/CN=diperm01,OU=people,DC=example,dc=com | The identity of the user in the directory server and the server that authenticated the user. |
| 7> Audit trail identifier: diperm01 | The user's audit trail identifier used in event logs caused by a session logged on as this user. |
| 8> Actual mechanism employed: ldap [OID 1.3.6.1.4.1.191.1.1012.1.20] | The name and Object Identifier (OID) of the actual authentication mechanism used to authenticate the user. The TDNEGO mechanism reports the actual mechanism that it selected to authenticate the user. Other explicitly named mechanisms report themselves here.
|
| 9> Mechanism specific data: diperm01 | 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. |
| 11 - 16> Security context capabilities: replay detection, ..., exportable security context | These lines show what a particular security context provides. The security context is the one established for the named user using the specified mechanism. |
| 18> Minimum quality of protection: None | The minimum quality of protection (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. |
| 19> 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. The has-policy value says that the user must use only a plaintext connection to the database and is used for very specialized purposes. The no-direct-connect value says that the user is not permitted to connect directly to the database. |
