Dear All,

Could this be as our LDAP is fairly short on attributes?

I note that a number of variables are included in this action, but which are 
required and which are optional is the question:

What would be the next step to help solve this issue? All users authenticating 
through LDAP get "This user is not authorised to perform authentication".

Ok I spoke too soon, I have resolved the groups, but authentication still isn't 
working for LDAP users, same error as before (114).

Dear Ondra, all,

Managed to solve this once i got my head around the properties file. 
Conceptually the problem is that users are typically not a member of their 
primary group in a POSIX scenario, and their primary group is set by the 
gidNumber of the user's record, with additional group memberships specified by 
memberUid entries against a posixGroup entry.

search.rfc2307-resolve-groups-memberUid.search-request.filter = 
&(objectClass=posixGroup)(|(memberUid=${seq:_rfc2307_uid_encoded})(gidNumber=${seq:_rfc2307_gid_encoded}))

search.rfc2307-resolve-principal-uid.search-request.attributes = uid, gidNumber

sequence.bmrc-resolve-groups.010.description = set dn
sequence.bmrc-resolve-groups.010.type = var-set
sequence.bmrc-resolve-groups.010.var-set.variable = _rfc2307_dn
sequence.bmrc-resolve-groups.010.var-set.value = ${seq:dn}
sequence.bmrc-resolve-groups.010.description = resolve uid
sequence.bmrc-resolve-groups.020.type = fetch-record
sequence.bmrc-resolve-groups.020.fetch-record.search = 
rfc2307-resolve-principal-uid
sequence.bmrc-resolve-groups.020.fetch-record.map.uid.name = _rfc2307_uid
sequence.bmrc-resolve-groups.030.description = resolve gid
sequence.bmrc-resolve-groups.030.type = fetch-record
sequence.bmrc-resolve-groups.030.fetch-record.search = 
rfc2307-resolve-principal-uid
sequence.bmrc-resolve-groups.030.fetch-record.map.gidNumber.name = _rfc2307_gid
sequence.bmrc-resolve-groups.040.description = query groups
sequence.bmrc-resolve-groups.040.type = search-open
sequence.bmrc-resolve-groups.040.search-open.search = 
rfc2307-resolve-groups-memberUid
sequence.bmrc-resolve-groups.040.search-open.variable = queryRFC2307ByMemberUid

sequence.rfc2307-resolve-groups.020.call.name = bmrc-resolve-groups

Callum

Dear Ondra,

I went for openldap-rfc2307 as that best describes our ldap setup. The issue 
seems to be that the gidNumber is set, but users are not a member of their 
primary group within the LDAP. So, user's gidNumber represents primary group 
and posixGroup membership (memberUid) represents their secondary groups. What's 
the best way to approach this (fix the filters on oVirt end or change the LDAP? 
This is a question of what is most compliant with standards really).

Regards,
Callum

What's you LDAP and what profile did you choose? This looks like you have 
chosen incorect profile during setup. Are you sure you arent using posix group 
and using non-posix aaa profile? Sharing a debug log of 
ovirt-engine-extensions-tool would be helpfull.

Dear All,

I'm having problems getting LDAP running, login works, but I'm getting "user is 
not authorised to perform login" - this is even if i specify the UserRole 
specifically to the LDAP group the user is in.

on a side note: is it possible to assign permissions to all members of an LDAP 
tree where they dont have a common group membership?

Callum
