The logoutput from the original smartcard-worker, compiled with opensc-pkcs11 library and another log with the output from the small hack i did just as a test.

Description of problem:
I'm trying to use the opensc-pkcs11 module together with our smart-cards, I've successfully managed to use it together with pam_pkcs11. pkcs11_inspect and login works. (The login part work with gdm, but that's not the issue) 

When I insert my card the first time (or if its inserted when gdm starts) I successfully get asked about my pin, this is what you would expect. However if I remove my smart-card whiteout typing my pin I would assume that gdm detects this and throws me back to the initial login (where i can choose between smartcard & other), that's the part that doesn't work. 

I ran gdm-smart-card-worker from the terminal and attaching the log-file. 
You can see at the end of the log that gdm-smart-card-worker is expecting slot_id not be 0, which it is in my case, don't really know why (if that is normal or if my setup is wrong), I've also posted this on the opensc list to see if they have an idea. 

I added the code if (slot_id == 0) {slot_id = 1}; just to see how gdm-smart-card-worker reacted,  it didn't die and actually reported that it detected each insert/removal, however gdm didn't do anything different. (throw me back to the "initial" login screen when card is being removed etc).

I would really like to have this working. Earlier we used a module from our cardvendors together gdm (with a small hack i did myself to get it working), however due too theirs negligent and incompetent support, I would like to use opensc driver instead. And I would also like to use the official packages from rhel6 and not hack them myself. 

I'm able to test any suggestions/patches or whatever that's necessary to get this working as expected. 

Two questions directly comes to my mind, 
# 1, Smartcard driver using spec 'library=/foo/' is configured at compile time, right ? This should really be configurable at run time, shouldn't it ? Not everyone is using the libcoolkeypk11.so that is used as default, or am i wrong ? 

# 2, Wouldn't it be a good idea to remove the smart-card patch (and others too) from the huuuge multistack patch ? I'm no programmer so i don't know if there is a specific reason for why it's like this, but I find it rather hard to work with, but again, maybe there is a reason for this.  


Version-Release number of selected component (if applicable):
gdm-2.30.4-5 

How reproducible:
Always. 

Steps to Reproduce:
1. Compile gdm-smartcard-worker to use /usr/local/lib/opensc-pkcs11.so
2. Try to get it to work with a standard card with SetCOS on it. 
3.
  
Actual results:
That gdm doesnt react on removals/insertions (except the first time)

Expected results:
That gdm reacts on every insertion/removals.
