Authentication through multiple sources

[kmuller]

I need to migrate a 8v2 environment (that uses a ldap for user         
authentication) into a 8v4 fp1 environment (that uses AD for           
configuration) without the user having to select their authentication   
source.   
                                                             
I need to be able to authenticate a user from either the ldap or the AD
without them selecting anything and have it as seemless as possible for
the user. 

Is this possible?  If so, how do I do it?

First of all... do you want to use ldap AND activedirectory or do you want to migrate from LDAP to AD?
If it's the last, you will have to recreate all users and memberships again (this because for a user in AD a GUID is used as a unique id, and these won't be the same as in your LDAP)... Sorry.... If you choose to use both at the same time, you could install 2 gateways which are bound to a specific namespace. The users will then have to log on to cognos 8 using e.g. http://<server>/cognos8ldap or http://<server>/cognos8ad
