Thanks. Here's the details:

# uname -a
Linux li1629-137 3.10.0-514.el7.x86_64 #1 SMP Tue Nov 22 16:42:41 UTC
2016 x86_64 x86_64 x86_64 GNU/Linux

# cat /etc/redhat-release
CentOS Linux release 7.3.1611 (Core)

#rpm qa | grep 'semanage'
libsemanage-2.5-5.1.el7_3.x86_64
libsemanage-python-2.5-5.1.el7_3.x86_64


I didn't make any changes to /etc/selinux/semanage.conf . Here's the content.
---
module-store = direct

# When generating the final linked and expanded policy, by default
# semanage will set the policy version to POLICYDB_VERSION_MAX, as
# given in <sepol/policydb.h>.  Change this setting if a different
# version is necessary.
#policy-version = 19

# expand-check check neverallow rules when executing all semanage commands.
# Large penalty in time if you turn this on.
expand-check=0

# usepasswd check tells semanage to scan all pass word records for
home directories
# and setup the labeling correctly.  If this is turned off, SELinux
will label /home
# correctly only.  You will need to use semanage fcontext command.
# For example, if you had home dirs in /althome directory you would
have to execute
# semanage fcontext -a -e /home /althome
usepasswd=False
bzip-small=true
bzip-blocksize=5
ignoredirs=/root
