I know this is an old thread, but I faced the same issue with NSL 7.0.2
/ iManager 2.7.4 and I figured out a better solution than reinstalling

- update iManager to the last FTF patch
- Install the sso.npm from your latest SecureLogin distribution
- Under the RBS, search for the installed module "SecureLogin SSO"
- Select it and click reinstall

It worked for me
