HTTPS generates back-end issues

Question

One of my old website is running TYPO3 v4.5. I bought a SSL certificate and my sys admin installed it on the server.

• the front-end is running well on https
• tha back-end login form runs weird : one time my login/password are ok, but sometimes it doesn't allow me to enter the back-end.

It is totally random and in Firebug, I have no clue in the console or in the network tab to help me. Same behavior for Chrome, FF or IE.

I tried a lot of parameters :

• [BE]LockSSL = 1
• [SYS][reverseProxyIP] with " ... "
• [SYS][reverseProxySSL] with " * "
• [SYS][cookieSecure] = 1

I event tried a lot of different combinations, with no success. Please notice that I also get a TYPO3 6.2 website and those parameters work perfectly on it. I guess that I am missing somthing for v4.5 ?

Check the BE cookieDomain configuration!
