YOu need not to revert back from Domain Auth to SRP.
SRP is always enabled, just login to Bl with RBACAdmins role and change domain auth to SRP for all users.
- RBACManager --> Users
- Open User and unselect the domain auth and select the SRP.
How many users you have?
actually, you can disable SRP in blasadmin under the authserver section, so you need to make sure it's enabled. and you'd need to change your login profile to use srp instead of domain auth.
you may also want to change the user names because they are probably like user@DOMAIN.COM.
