Description of problem:
SELinux is preventing /usr/sbin/gssproxy from 'read' accesses on the lnk_file /usr/lib64/libcrypt.so.1.

*****  Plugin restorecon (94.8 confidence) suggests   ************************

If you want to fix the label. 
/usr/lib64/libcrypt.so.1 default label should be lib_t.
Then you can run restorecon.
# /sbin/restorecon -v /usr/lib64/libcrypt.so.1

*****  Plugin catchall_labels (5.21 confidence) suggests   *******************

If you want to allow gssproxy to have read access on the libcrypt.so.1 lnk_file
Then you need to change the label on /usr/lib64/libcrypt.so.1
# semanage fcontext -a -t FILE_TYPE '/usr/lib64/libcrypt.so.1'
where FILE_TYPE is one of the following: admin_home_t, bin_t, boot_t, cert_t, device_t, devlog_t, etc_runtime_t, etc_t, file_context_t, fonts_cache_t, fonts_t, gssproxy_var_lib_t, gssproxy_var_run_t, ld_so_t, lib_t, locale_t, man_cache_t, man_t, net_conf_t, proc_t, root_t, rpm_script_tmp_t, security_t, shell_exec_t, src_t, sssd_var_lib_t, system_conf_t, system_db_t, textrel_shlib_t, tmp_t, usr_t, var_run_t, var_t. 
Then execute: 
restorecon -v '/usr/lib64/libcrypt.so.1'

*****  Plugin catchall (1.44 confidence) suggests   **************************

If you believe that gssproxy should be allowed read access on the libcrypt.so.1 lnk_file by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
allow this access for now by executing:
# grep gssproxy /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
