Grouper Users - Open Discussion List

[Chris Hyzer <>]

Argh!  Im really sorry, Im looking at the doc test cases:

 

https://spaces.internet2.edu/display/Grouper/Grouper+-+Loader+LDAP#Grouper-LoaderLDAP-LDAPGROUPLISTtestcase

 

I misread the Java source, the correct syntax is:

 

groups:${loaderLdapElUtils.convertDnToSubPath(groupAttributes['dn'], null, null)}

 

if you just want the dn in your case, try this:

 

${udemLoaderElUtils.convertDnToGroupName(groupAttributes['dn'])}

 

You probably get access to other group attributes as well (cn, etc)

 

I verified this works:

 

Note, I guess the top stem is always the stem where the group is which controls the job… hmmm

 

 

grouperSession = GrouperSession.startRootSession();

group = new GroupSave(grouperSession).assignName("anotherStem:groupListLdapGroup").assignCreateParentStemsIfNotExist(true).save();

attributeAssign = group.getAttributeDelegate().assignAttribute(LoaderLdapUtils.grouperLoaderLdapAttributeDefName()).getAttributeAssign();

attributeAssign = group.getAttributeDelegate().retrieveAssignment(null, LoaderLdapUtils.grouperLoaderLdapAttributeDefName(), false, true);

attributeAssign.getAttributeValueDelegate().assignValue(LoaderLdapUtils.grouperLoaderLdapTypeName(), "LDAP_GROUP_LIST");

attributeAssign.getAttributeValueDelegate().assignValue(LoaderLdapUtils.grouperLoaderLdapFilterName(), "(|(cn=test:testGroup)(cn=test:ldaptesting:test1))");

attributeAssign.getAttributeValueDelegate().assignValue(LoaderLdapUtils.grouperLoaderLdapQuartzCronName(), "0 * * * * ?");

attributeAssign.getAttributeValueDelegate().assignValue(LoaderLdapUtils.grouperLoaderLdapSearchDnName(), "ou=groups");

attributeAssign.getAttributeValueDelegate().assignValue(LoaderLdapUtils.grouperLoaderLdapServerIdName(), "personLdap");

attributeAssign.getAttributeValueDelegate().assignValue(LoaderLdapUtils.grouperLoaderLdapSourceIdName(), "pennperson");

attributeAssign.getAttributeValueDelegate().assignValue(LoaderLdapUtils.grouperLoaderLdapSubjectAttributeName(), "hasMember");

attributeAssign.getAttributeValueDelegate().assignValue(LoaderLdapUtils.grouperLoaderLdapSubjectIdTypeName(), "subjectIdentifier");

attributeAssign.getAttributeValueDelegate().assignValue(LoaderLdapUtils.grouperLoaderLdapExtraAttributesName(), "cn");

attributeAssign.getAttributeValueDelegate().assignValue(LoaderLdapUtils.grouperLoaderLdapGroupNameExpressionName(), "groups:${loaderLdapElUtils.convertDnToSubPath(groupAttributes['dn'], null, null)}");

group = GroupFinder.findByName(grouperSession, "anotherStem:groupListLdapGroup");

loaderRunOneJob(group);

getGroups("anotherStem")

I updated some of the docs to reflect this

 

Thanks,

Subject: RE: Loader LDAP - Group name _expression_

 

Thanks, but I tried it again and there’s still a problem :

 

LDAP extra attributes = distinguishedName,dn,cn

LDAP group name _expression_ = ${udemLoaderElUtils.convertDnToGroupName(distinguishedName)}

 

I get these exceptions :

2012-06-05 08:08:16,266: [main] ERROR GrouperLoaderJob.runJobLdap(537) -  - Error on job: LDAP_GROUP_LIST__etc:confLDAPLoader__e7b97262558b477fab09c0b48f98ed1c

I tried with both distinguishedName, dn, cn and subjectId, and all of them give me an “undefined variable” error.

Almost got it J

 

${udemLoaderElUtils.convertDnToGroupName(dn)}

 

I think there is a built-in that might do this too, not sure:

 

${loaderLdapElUtils.convertDnToGroupName(dn, null, null)}

 

If you want some of it stripped off, put that as an arg:

 

${loaderLdapElUtils.convertDnToGroupName(dn, “,dc=school,dc=edu”, null)}

 

Let me know if it works

 

Thanks,

Chris

Subject: [grouper-users] Loader LDAP - Group name _expression_

 

Hello,

When configuring the Loader LDAP, how can you specify the stem where the LDAP structure will be provisioned ? It seems that the attribute “grouperLoaderLdapGroupNameExpression” is the way to go, but I can’t seem to configure it properly.

 

If I leave it empty, I have my bushy LDAP structure, but not in the right base stem, i.e.

 

groups

- stem1

  - group1

   - stem11

     - group2

- stem2

   - stem21

     - group3

 

What I would like to have is the same thing, but with a different base stem. I tried with :

 

grouperLoaderLdapGroupNameExpression =  udem:${groupAttributes['cn']}

 

But I get a flat structure under etc (the stem where my loaderLdap configuration group is)

etc

  - udem

    - group1

    - group2

    - group3

 

I tried using a custom class which builds the proper bushy group name with the right base stem, but each of the following gives me an error when the loader starts

 

grouperLoaderLdapGroupNameExpression

= ${udemLoaderElUtils.convertDnToGroupName(${groupAttributes['dn']})}

= ${udemLoaderElUtils.convertDnToGroupName(groupAttributes['dn'])}

= ${udemLoaderElUtils.convertDnToGroupName(subjectId)}

= ${udemLoaderElUtils.convertDnToGroupName(['dn'])}

= ${udemLoaderElUtils.convertDnToGroupName('dn')}

= udemLoaderElUtils.convertDnToGroupName(${groupAttributes['dn']})

(this last one does not fail, but does the same thing as the flat structure above, but with a huge prefix (udemLoaderEl…) )

 

 

I successfully used this class with the Subject _expression_ and don’t understand why it doesn’t work with the group name _expression_ :

grouperLoaderLdapSubjectExpression = ${udemLoaderElUtils.convertAdMemberDnToSpecificValue(subjectId)}

 

 

Thank you for you help
