The following issues are observed with NCM policy manager:
DX NetOps Spectrum 20.2.x and later
Since these user models exist on the non MLS SpectroSERVER, they take some time to sync user model attributes with the MLS. To resolve this, the user models need to have ADMIN,0 Legacy security string. You may need to do an SS restart if this string is not properly updated/sync'd.
After updating the attribute, wait for around 5min and refresh the subview and see if the string is properly updated (not over-written with old string).
As a test, do a Policy test this with one user. Then you can update for all user groups/independent users. Also, you can test on user access restriction with two users in which one has restricted access to some functions and other has no restriction. It should behave same before and after updating the legacy snmp comm string with "ADMIN,0".
