Tried adding ACLs on to NetScaler (13.1-51.15) and when trying to apply the ACLs I'm getting this:
`> apply acls`
`Warning: Config NodeGroup changed, force cluster sync should be fired on newly added node to be in sync []`
 `Done`

Has anyone else ran in to the same problem? I got one through, but now I'm no longer able to add these. This is a HA setup in Azure (not a cluster).

Opened a case and got a quick answer:
"From the case description, I understand that you are getting error "Config NodeGroup changed, force cluster sync should be fired on newly added node to be in sync" while applying the ACLs.
This is a known issue. BUG ID NSHELP-15668.
If using "! =" Operation identifier, the number of associated ACLs or the number of entries in the dataset associated with ACLs exceeds 15.
This results in this error "Config NodeGroup changed, force cluster sync should be fired on newly added node to be in sync []"
As a workaround, please try to switch the ACL from the blacklist to the whitelist , Avoid using "! =" Operation identifier."
