Subject: Import dlpam_sterror symbol.
X-Git-Tag: 2011.09.23-491607~10
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=5bd57a8bb954902a8ab2d23439ea04dc6cd2dd54;p=thirdparty%2Fopen-vm-tools.git

Import dlpam_sterror symbol.

When the user executes any guest operation with invalid login
credentials, vmtoolsd process crashes [Signal 11, Segmentation fault].
Got the stack trace and found out that the crash happens in
Auth_AuthenticateUser() function. dlpam_strerror symbol is not loaded
from the PAM library but is referenced. This causes the crash.

Modified the code to import the dlpam_sterror symbol.
