For the All Realms sequence, you can only change the order of its realms, you cannot change 
the realms themselves. To change the order of realms in the All Realms sequence, click the 
arrows in the Order column to reposition the corresponding realms.

Repeat Step 3 until all realms are listed and ordered as required, ensuring that each realm name appears 
in one row only.

Submit and commit your changes.

Be aware that deleting an authentication sequence also disables associated identities, which in turn 
removes those identities from associated policies.

Choose Network > Authentication.

Click the trash can icon for the sequence name.

Click Delete to confirm that you want to delete the sequence.

Commit your changes.

Users may be blocked from the web due to authentication failure for the following reason:

Client limitations. Some client applications may not properly support authentication. You can 
bypass authentication for these clients by configuring Identities that do not require authorization and 
basing their criteria on the clients (and, optionally, on the URLs they need to access). 

Authentication service is unavailable. An authentication service might be unavailable due to 
network or server issues. You can choose to allow unauthenticated traffic in this circumstance. 

Invalid credentials. Some users may be unable to supply valid credentials for proper authentication 
(for example, visitors or users awaiting credentials). You can choose to grant these users limited 
access to the web.
