Login if LDAP not available

[RiRo]

Hello Community!

I installed Cognos Analytics V11 and added a LDAPS connection to a MS LDAP Directory.
Now I have added an Active Directory group to the Cognos/System Administrators role.

My question is, because there is no local userrepository on this machine,
what is if MS LDAP directory isn't available? How can I log on, maybe the AD group was deleted by an accident?

How can I define a local user, with that I can login to Cognos, even if there is a problem with groups or AD paths?

Thanks
Robert
