pam_mysql 0.4.7 which has been patched to allow for crypt passwords and 
md5 hashes. My previous server had both types stored. I suppose one 
would be to move to a more stable (newer) version of pam_mysql. However, 
my patch only seems to work with this version. I do remember trying 
version 0.5 with not much luck. I have a spare box I'm going to retry with.

If I could convert the md5 hashed passwords to crypt ones I may be able 
to get around it. This is another reason I hesitant to move to auxprop. 
Needs a little more research. Any tips on how to tell if there are 
memory leaks in pam_mysql?

Sorry, I'm not familiar with that phrase. Do you mean I need to define 
somewhere in the configuration or compile time /dev/random or 
/dev/urandom? I see the compile option in cyrus-sasl. Am I barking up 
the wrong tree?

Thanks for your help.
