# Add container for automembers plugin
ldapmodify -h $IP -p $PORT -D "cn=directory manager" -w Secret123 -a <<EOF

dn: $PLUGIN_AUTO
changetype: modify
add: nsslapd-pluginConfigArea
nsslapd-pluginConfigArea: $ROOT
-
replace: nsslapd-pluginEnabled
nsslapd-pluginEnabled: on
EOF


# Add rules that conlict with pluginConfigArea
ldapmodify -h $IP -p $PORT -D "cn=directory manager" -w Secret123 -a <<EOF
dn: cn=replsubGroups,$PLUGIN_ROOT
objectclass: autoMemberDefinition
autoMemberScope: cn=Employees,$ROOT

autoMemberExclusiveRegex: uidNumber=^[1,3,8]99$
autoMemberExclusiveRegex: gidNumber=^[2-4]00$

EOF


Actual results: Automembership plugin accepts invalid configuration. It requires a server restart to reject the configuration.


Expected results: Plugin should reject the invalid configuration dynamically.
