LDAP servers for fault tolerance only?

L2 Linker

Dear community,

 

I am struggling around with a though I cant find an answer for. I every documentation I found they state that additional LDAP server are for fault tollerance only. Imagine the follwing setup:

 

A customer is loadbalancing user authentication against more than one LDAP servers.

 

So actually that means the firewall will only monitor one of maximum 4 LDAP servers (per profile). Think about all of the servers are up and running but user logon is distributed across all four LDAP servers. How will I be able to discover complete user ID information?

 

Kind regards,

 

Rene

I think you're mingling 2 concepts of the ldap server, being group membership information and userID information

 

the ldap profiles can be used to extract groups, users and group membership from the ldap server. in the ldap profile one server is used for retrieval and authentication, as all servers in the profile should contain the same information (the ldap tree with all the groups and users for it's domain)

 

userID does not use the ldap profile: user to IP mapping is gained through UserID agents, Captive portal, API calls ,.. and only after the firewall gains a user-ip mapping is the user matched to a user object and group membership obtained through the ldap

 

so no information should be lost unless your ldap servers do not replicate their ldap tree information

 

for UserID information, all 4 servers should be polled by a UserID agent to detect the distributed logins
