verified using steps:
# rpm -q --provides samba4-libs | grep libsmbclient
libsmbclient-raw.so.0()(64bit)  
libsmbclient-raw.so.0(SMBCLIENT_RAW_0.0.1)(64bit)  
libsmbclient.so.0(SAMBA_4.0.0RC4)(64bit)  
libsmbclient.so.0(SMBCLIENT_0.1.0)(64bit)  
libsmbclient.so.0(SMBCLIENT_0.2.0)(64bit)  

# rpm -q --provides samba4-libs | grep libwbclient
libwbclient.so.0(SAMBA_4.0.0RC4)(64bit)  
libwbclient.so.0(WBCLIENT_0.10)(64bit)  
libwbclient.so.0(WBCLIENT_0.9)(64bit)  

# rpm -q --provides samba4-libs | grep libnetapi
libnetapi.so.0(SAMBA_4.0.0RC4)(64bit)

do the above steps verify this bz?

See bug #861892. The difference here is that the rule was incomplete. The linker produces different symbol names on different architectures. 64bit is different to 32bit package, so you need to check both platforms.

on 64bit:
# rpm -qa | grep samba
samba4-libs-4.0.0-55.el6.rc4.x86_64
samba-common-3.6.9-151.el6.x86_64
samba-winbind-3.6.9-151.el6.x86_64
samba-winbind-clients-3.6.9-151.el6.x86_64

# rpm -qa | grep libsmbclient
libsmbclient-3.6.9-151.el6.x86_64


on 32bit:
# rpm -qa | grep samba
samba-common-3.6.9-151.el6.i686
samba-winbind-3.6.9-151.el6.i686
samba4-libs-4.0.0-55.el6.rc4.i686
samba-winbind-clients-3.6.9-151.el6.i686

# rpm -qa | grep bclient
libsmbclient-3.6.9-151.el6.i686
