Limit of .tokens in AEM6.3 for User via SAML Authentication

[rawvarun]

Hi,

Is there any limit of active .tokens in AEM 6.3 for User via SAML Authentication.

As of now, I'm not able to log in if rep:user in AEM via SAML Authentication is having more than 300  active .tokens.

The above users are all CUG users.
