Description (partial)

When you have usernames in format of hex numbers like: a01146837d5f (random example), those will get disabled due to 'disable account policy' despite the fact that those users log in on regular basis. When such a user does AAA/Tacacs via ISE, you can see the usernames are translated to the form a0:11:46:83:7D:5f when written to the MnT tables. This causes a mismatch with the original username, so the last active time is not updated.

1 Usernames in hex format
2 Disable account policy configured.
