Entering Cisco SNMPv3 passwords in digest form

Has anyone successfully been able to enter your SNMPv3 passwords in digest form?

My SNMPv3 works when passwords are entered in clear text, but when entered in SHA digest form, SNMPv3 tests fail.

Cisco says this can be done (scroll down a little to "Working with Passwords and Digests")

The format I'm entering is as follows:

SNMP-Server user testuser SNMPv3Group v3 auth SHA db:fa:10:bc:69:69:59:6d:3d:d4:71:9d:5f:65:fd:c2 priv AES 256 30:a4:c7:c7:df:a2:28:88:7d:a0:13:ce:73:9c:1d:0a access 30

​

I'm creating the SHA1-96 digests by discarding the last 4 octets of SHA1 digests.
