802.1x with certificates - problems

[blind_oracle]

There's no need, thanks. I've got to the root of the problem:
1. When the phone boots, it defaults it's time to 00:00:00 and date to the last date it knew (today)
2. It checks server certificate that was issued *today* too, but ,for example, at 12:00, so from the phone's perspective it's not yet valid.

So it's enough to wait 1 day for the date to move to the next day and it started to work fine.
