There is a known working samba share.  There are servers that connect to it.  All of them happen to be Windows boxes.  However, wanted to connect a Linux (CentOS 7) to it.  When testing for a connection, it failed with an error message.

The command and the error.

[root@c7client app]# smbclient -L 10.10.10.10
smbclient: relocation error: /lib64/libsamba-credentials.so.0: symbol GSS_KRB5_CRED_NO_CI_FLAGS_X, version gssapi_krb5_2_MIT not defined in file libgssapi_krb5.so.2 with link time reference

The resolution turned out to be a simple one.  Update the client system.

yum -y update

Repeat the same command above and you should be prompted with a password.
