Re: Chain authentication bind configuration
This worked perfect. The flag "non-prescriptive" was exactly what I needed
to statically-force the binddn for the chain. The end use for this is an
LDAP server which acts as a "superroot" tree for multiple active directory
systems in an 802.1x switch authorization service.
Thanks for your help Gavin.
