Title: Configuring Multiple LDAP or Active Directory Servers
In some cases it might be necessary to check multiple LDAP or Active
Directory servers to locate and authenticate all of the users. As some
searches will require looking in all
of the LDAP servers, where possible you should consolidate the users into
a single directory or rely on replication capabilities provided by your
directory.
Using the Additional Settings
field in the Advanced Settings
section of the configuration, add the following settings for additional
directories. Do not repeat the original configuration here, just add additional
ones.
For each additional server, increment the number of the prefix (ldap1_server=
...). If any value is unspecified, it will default to the value provided
with the ldap_ prefix. For example, if ldap_authentication=simple and
ldap0_authentication= is not specified, ldap0 will use simple authentication.
It might help to look at the generated configuration file. To open the
generated file, click the link in the upper left portion of the configuration
dialog, below the title of the configuration.
