| 1 | User ID For IPMI v2.0, the BMC shall support 20-byte passwords (keys) for all supported user IDs that have configurable passwords. The BMC shall maintain an internal tag that indicates whether the password was set as a 16-byte or as a 20-byte password A 16-byte password can be used in algorithms that call for a 20-byte password. In this case, the 16-byte password is padded with 0's to 20-bytes The 'test password' operation shall return the 'test failed' error completion code if an attempt is made to test a password that was stored as a 20-byte password as a 16-byte password (per 'passwordsize' bit 7), and vice versa A password that has been stored as a 20-byte password cannot be used for establishing an IPMI v1.5 session. If it is necessary to configure the same password for both IPMI v2.0 and IPMI v1.5 access, it must be set as a 16-byte password5. The password will be padded with 0's as necessary for IPMI v2.0/RMCP+ use The 'test password' operation can be used to determine whether a password has been stored as 16-bytes or 20-bytes [7]-password size 1b=set 20-byte user password/key 0b=set 16-byte user password/key (IPMI v1.5 backward compatible) [6]-reserved [5:0]-User ID. 000000b=reserved. (User ID 1 is permanently associated with User 1, the null user name) |
| 2 | [7:2]-reserved [1:0]-operation 00b=disable user 01b=enable user 10b=set password 11b=test password Compares the password data given in the request with the presently stored password and returns an OK completion code if there is a match. Otherwise, an error completion code is returned. (See the Completion Code description in the response data.) |
| For password size=16 bytes: | |
| 3:18 | Password data. This is a required, fixed length field when used for the setand test password operations. If the password is entered as an ASCII string, it must be null (00h) terminated and 00h padded if the string is shorter than 16 bytes. This field need not be present if the operation is ‘disable user’ or ‘enable user’. If this field is present for those operations, the BMC will ignore the data. |
| For password size=20 bytes: | |
| 3:22 | 20-byte Password data. This is a required, fixed length field when used for the set- and test password operations. If the password is entered as an ASCII string, it must be null (00h) terminated and 00h padded if the string is shorter than 20 bytes. This field need not be present if the operation is ‘disable user’ or ‘enable user’. If this field is present for those operations, the BMC will ignore the data. |
