Hello,
Thanks again but this time I will not be so quick to fix the issue.
I don't have access to Couchbase > 5.0 right now and my company don't plan to buy it as the liscencing/pricing have changed with this new version.
I will try to look at the issue when I have some time in order to judge the amount of work needed to support couchbase > 5.0

I will keep you updated, but for now the only way I guess is to use the Admin user/password

[zhxiaom5]

well，enterprise is free for test，and i have used the admin user and password，maybe its the access rules has changed
