I've been having the "incorrect password" problem as well the first time I tried to log in. It almost always worked on the second attempt.
Your discussion about the https above had me look t things closer and I noted that the shortcut I had brought me to an "unsecure" version of the login page. I've now deleted that and replaced my link with the one above and so far it seems to log me in properly the first time. I'll keep an eye out.
I have not been @ army.ca in awhile and not using a shortcut, I typed army.ca in the location bar, hit enter and the page brought me to the "Guest" page and I thought I must have deleted my cookies, so I clicked on 'login'. It also gave me that the login username was not secure and sure enough at the location bar (Firefox) it indicated it was not a secure page. I did not attempt to login, but looked in the Admin folder and found your post.
Using the link provided gave me a secure Login page and here I am!
Something must be amiss.
