Description
for example, if we use
1. Check jaas:realms (select module PropertiesLoginModule) 2. jaas:manage --index 1 3. jaas:useradd foo foo 4. jaas:groupcreate cool 5. jaas:groupcreate cool 6. jaas:groupadd foo cool 7. jaas:groupadd foo cool
then in the etc/users.propertries we can see
foo = foo,_g_:cool,_g_:cool
the duplicated group for foo should be avoided
