We didn't see any LDAP errors. Also, we were querying a no-limit server, which was responding quickly (that attribute is indexed). Using a query on the same attribute to simply populate a single group works fine.

We are new to Grouper, and might have something dumb in our group definition.

Check your LDAP server logs for any error (error message or LDAP error code) associated with that particular query:

(|(umichInstRoles=FacultyAA)(umichInstRoles=StudentAA))

Maybe it timed out (either on the LDAP server or client side) or it exceeded some threshold on the number of entries it can return or search through.

We're just starting to explore grouper.  Based on the example at https://spaces.internet2.edu/display/Grouper/Grouper+Loader+LDAP+examples#GrouperLoaderLDAPexamples-LDAPgroupsfromattributes, we tried to set up a "groups from attributes" definition:

LDAP filter (|(umichInstRoles=FacultyAA)(umichInstRoles=StudentAA))
LDAP group attribute name umichInstRoles
LDAP group name _expression_ groupsFromAttributes:${groupAttribute}
LDAP search base DN ou=People,dc=umich,dc=edu
LDAP server ID mcommDir
LDAP source ID mcommDir
LDAP subject ID type subjectIdentifier
LDAP subject attribute name entityid
LDAP type LDAP_GROUPS_FROM_ATTRIBUTES

We see the searches:

2016-12-23 12:17:54,281: [ajp-apr-8009-exec-4] DEBUG GrouperLoaderConfig.retrieveLdapProfile(317) -  - LDAP config for server id: mcommDir: GrouperLoaderLdapServer [batchSize=-1, configFileFromClasspath: , countLimit=-1, driver=null, expirationTime=-1, maxPoolSize=-1, minPoolSize=-1, pagedResultsSize=-1, pass=XXXXX, pruneTimerPeriod=-1, referral=, saslAuthorizationId=null, saslRealm=null, timeLimit=-1, timeout=-1, tls=false, url="ldaps://ldap.umich.edu, user=cn=Grouper,ou=Applications,o=Services, validateOnCheckIn=false, validateOnCheckOut=true, validatePeriodically=false, validateTimerPeriod=-1]

Then we get back a stacktrace that's not particularly helpful (at the end of the message).

Can anyone point us in the right direction?
