Good afternoon,

We cannot access to Ovirt using LDAP authentication against our openldap
server. We created the following files in /etc/ovirt-engine/extensions.d

After all of this we restarted the service and tried to access via the
administration portal. The JKS has the right permissions and contains
the TLS CA, the password is correct and the user "esthera" exists. But
when we try to log in, we obtain the following error in the engine.log
(we already set the verbosity to ALL):

------------------------------------------------

Having a look at the LDAP log we check that there is a "invalid
credentials" error while binding, but we are sure that the bind password
is the right one. We already tried to set the bind password without
quotes, but then the DN user then appear as an empty string ("")

I think problem is here. That's really strange, you have to use the password without quotes.

Can you please try to set:
pool.default.auth.simple.bindDN = cn=authenticate,ou=System,dc=example,dc=org
pool.default.auth.simple.password = XXXXXX

just without the variables. if the DN is not empty now.

------------------------------------------------

By the way, the Ovirt manager (ovmgr) machine can query correctly the
openldap server and retrieves everything OK

------------------------------------------------

[root@ovmgr extensions.d]# ldapsearch -ZZ -D
cn=authenticate,ou=System,dc=example,dc=org -W
Enter LDAP Password:
# extended LDIF
#
# LDAPv3
# base <dc=example,dc=org> (default) with scope subtree
# filter: (objectclass=*)
# requesting: ALL
#

# pic.es <http://pic.es/>
dn: dc=example,dc=org
dc: pic
objectClass: top
objectClass: domain

------------------------------------------------

Did anybody had a similar problem ? Is there anything that we didn't check ?

Thanks in advance !
