This should be the correct fix for the valgrind erorr Volker found in 744ed53a62037a659133ccd4de2065491208ae7d. This fix avoids putting SPNEGO into the list twice when we are in the CRED_DONT_USE_KERBEROS case. Andrew Bartlett

2011-12-03Revert making public of the samba-module library.Jelmer Vernooij2-8/+8
This library was tiny - containing just two public functions than were themselves trivial. The amount of overhead this causes isn't really worth the benefits of sharing the code with other projects like OpenChange. In addition, this code isn't really generically useful anyway, as it can only load from the module path set for Samba at configure time. Adding a new library was breaking the API/ABI anyway, so OpenChange had to be updated to cope with the new situation one way or another. I've added a simpler (compatible) routine for loading modules to OpenChange, which is less than 100 lines of code.
