Description of problem:

realm leave parses the sssd.conf incorrectly if multiple ad_sever is set. realmd seems to take the value in ad_server and substitute in adcli command:

sssd.conf:
ad_server= svwircaa.rese-admin.colruyt.int, svwircab.rese-admin.colruyt.int

===

realm leave rese-admin.colruyt.int --remove -U bp1
