I can't join ADS after yum update.
The system-config-authentication responses below
----------------------begin--------------------------------------
kinit succeeded but ads_sasl_spnego_gensec_bind(KRB5) failed for ldap/xxxx with user[xxxxx] realm[xxxxx]: An invalid parameter was passed to a service or function.
Failed to join domain: failed to connect to AD: An invalid parameter was passed to a service or function.
ADS join did not work, falling back to RPC...
-----------------------end-------------------------------------

The sequences below:
yum update returned below
-----------------------begin-----------------------------------
エラー: パッケージ: gnome-classic-session-3.26.2-3.el7.noarch (rhel-7-workstation-rpms)
要求: gnome-shell-extension-top-icons = 3.26.2-3.el7

yum can be configured to try to resolve such errors by temporarily enabling
disabled repos and searching for missing dependencies.
To enable this functionality please set 'notify_only=0' in /etc/yum/pluginconf.d/search-disabled-repos.conf

------------------------end------------------------------------
