Grouper Users - Open Discussion List

[Jeffrey Williams <>]

I'm currently cutting my teeth on PSPNG as well, so you're not alone!

This particular line is of interest to me:

errorMessage='object class 'groupOfNames' requires attribute
'member'', diagnosticMessage='object class 'groupOfNames' requires
attribute 'member'')

From my limited observation, it seems that PSPNG is more a breadth-first sort of provider, where it'll provision empty groups first then come back and add members as an update(someone call me out on this if I'm wrong).  If your groupOfNames requires member values up front, that may pose a problem.  If you set your member attribute to me optional in groupOfNames and rerun PSPNG, does the issue re-occur?

Hi,

After my rather hasty email yesterday I've made a little bit of progress
and now have PSPNG connecting to LDAP. It's currently failign to
add/modify groups due to lack of members:

And on the LDAP side the error is:

dn="cn=adhoc:MCTest:Mark 1,cn=Mark
1,ou=MCTest,ou=adhoc,ou=grouper2,dc=authorise-dev,dc=ed,dc=ac,dc=uk"
Dec  6 11:45:00 bonsai slapd[34260]: Entry (cn=adhoc:MCTest:Mark
1,cn=Mark
1,ou=MCTest,ou=adhoc,ou=grouper2,dc=authorise-dev,dc=ed,dc=ac,dc=uk):
object class 'groupOfNames' requires attribute 'member'


1. As provisioned by PSP the DN of the group is:
cn=Mark
1,ou=MCTest,ou=adhoc,ou=grouper2,dc=authorise-dev,dc=ed,dc=ac,dc=uk" so
this should actually be a modify rather than an add.

My PSPNG currently contains the line:
dn: cn=${group.name},${utils.bushyDn(group.name, "cn", "ou")}||cn:
${group.name}||objectclass: posixGroup||objectclass:
groupOfNames||gidNumber: ${group.idIndex}

How should this be modified to replicate the previous behaviour for the DN?

2. I've got the following in my grouper-loader.properties:
changeLog.consumer.pspng_cauth.memberAttributeName = member
changeLog.consumer.pspng_cauth.memberAttributeValueFormat =
${ldapUser.getDn()}

However I don't see any attempts at looking up users in LDAP, only the
group. Also is there a way to define a "placeholder" member for empty
groups? How does PSPNG resolve grouper members with LDAP/AD users?

Sorry for all the questions- I'm sure there  will be more though once I
get over this particular speed-bump!
