And for what it's worth, it's not used by the dwarves tools.
It's actually in good company:

Symbol memdup@@ (64-bit UNIX System V ABI AMD x86-64 architecture) present 7 times
  /usr/lib64/libnetsnmp.so.15.1.0
  /lib64/security/pam_smbpass.so

  /usr/lib64/libdwarves.so.1.0.0
  /usr/lib64/samba/security/pam_smbpass.so
  /usr/lib64/samba/libsmbclient.so

It should probably be hidden anyway.
