Hello, I'm bringing up a new 4.2 cluster and would like to use LDAP auth. Our LDAP servers are fine and function normally for a number of other services, but I can't get this working. Our LDAP setup requires startTLS and a login. That last bit seems to be where the trouble is. After ovirt-engine-extension-aaa-ldap-setup asks for the cert and I pass it the path to the same cert used via nslcd/PAM for logging in to the host, it replies: [ INFO ] Connecting to LDAP using 'ldap://x.squaretrade.com:389' [ INFO ] Executing startTLS [WARNING] Cannot connect using 'ldap://x.squaretrade.com:389': {'info': 'authentication required', 'desc': 'Server is unwilling to perform'} [ ERROR ] Cannot connect using any of available options "Unwilling to perform" makes me think -aaa-ldap-setup is trying something the backend doesn't support, but I'm having trouble guessing what that could be since the tool hasn't gathered sufficient information to connect yet - it asks for a DN/pass later in the script. And the log isn't much more forthcoming. I double-checked the cert with openssl; it is a valid, PEM-encoded cert. Before I head in to the code, has anyone seen this?
