ok. Saw these notes in the errata.
1) configure system for smart card/username-password login
2) go to login screen
3) insert smart card
4) while the text entry field is grayed out and you see 3 dots (this is when
pam_pkcs11 is connecting to the card), remove the smart card
If the timing is right, you'll get an "Authentication Failed" message with the
old packages, but not with the new ones

So I tried the steps mentioned in comment #17. Exactly when I see the ...(3dots),
I pulled out the smart card. After that the gdm login screen is unable to
recognize insertion/removal events.
re-assigning back to Ray to see why ...

ray enabled gdm debug logging and I wasn't able to reproduce this problem.
Feels like this is very much related to timing. Ray will continue to investigate

So, I spent some time banging on this yesterday, while talking to Chandra, Jack
and Bob on irc.
I couldn't reproduce the problem Chandra is seeing exactly (not surprising since
it's apparently timing related), but there is another similiar issue we ran into.
If you remove and insert the card 32 times (that is 16 removes and 16 inserts)
then PK11_IsPresent() from that point on will always return false which means
neither gdm nor pam_pkcs11 will see the card inserted anymore.
At any rate, that problem and Chandra's problem in comment 18 are independent of
the original issue, so we should file them as separate bugs (tentatively against
pcsc-lite i guess until we figure out where in the stack the problem is).
Those issues aren't likely to get resolved for 5.2 since they're problems with
components not on the approved component list and it's so late in the
PCSC lite has many resources limited to 16. So if gdm (or another layer) is consuming resources without
freeing them when needed you can have a problem.
In such a case the PCSC function (SCardEstablishContext() for example) should return SCARD_E_NO_MEMORY
