Subject: [PATCH] doc: Update LDAP grace period design with default values
New group password policies will get -1 (unlimited) on creation
by default.
Existing group password policies will remain untouched and
those created prior will be treated as no BIND allowed.
Fixes: https://pagure.io/freeipa/issue/9212

On successful password reset (by anyone) reset the user's passwordGraceUserTime to 0.
-The default value on install/upgrade will be -1 to retail existing behavior.
+Range values for passwordgracelimit are:
+
+-1 : password grace checking is disabled
+ 0 : no grace BIND are allowed at all post-expiration
+ 1..MAXINT: the number of BIND allowed post-expiration
+
+The default value for the global policy on install/upgrade will be -1 to
+retain existing behavior.
+
+New group password policies will default to -1 to retain previous
+behavior.
+
+Existing group policies with no grace limit set are updated to use
+the default unlimited value, -1. This is done because lack of value in
+LDAP is treated as 0 so any existing group policies would not allow
+post-expiration BIND so this will avoid confusion.
The per-user attempts will not be replicated.
