Do you think it's possible to kick off a long running operation, and while it's running call jstack on the process id and send me the output.  There should not be a problem with the act as, it should just lookup the authenticating subject...

Hi Chris,

I'm using GcHasMember() and GcGetMembers() to get users from the group. In the, I am only using = etc:servicePrincipals: 

I am setting up the environment to debug further, couple more questions:
  • Any idea if GcHasMember() and GcGetMembers() some how calling actAs method? or Is there work around?
Thank you,

Might be searching your sources for the logged in subject.  Still a little concerning if a subject lookup takes that long.


Can you try setting this in


# if you have subject namespace overlap (or not), set the default subject

# sources (comma-separated) to lookup the user if none specified in user name =


Put the source id of the source that the logged in subject should be in.  If it is LDAP then this wont help…


When you do a search in GSH for the logged in subject does it take a while?  Maybe tune your subject source?


Just curious is your web service request using an actAs?

Hi Chris,


I troubleshoot the timeout error and pinpoint to the Class ==>  getSearchReply(LdapRequest, int, LdapResult, Hashtable) method. The part that I'm not sure is why does Grouper WS searching LDAP, any idea?


I added a screenshot below that pinpoint error method:




Any guidance to fixed the timeout issue is truly appreciated. 


Thank you,

do you see a timeout setting in the client you can increase?  

can you analyze tables in the grouper database to make calls quicker?  maybe bounce the WS?  rebuild indexes?

Hi Chris,


Currently, I am working on integrating the application with the Grouper WS. When I run the application, it takes around 20-30 seconds (a little longer) to get a response from the WS and after some times, it throws an error (Caused by: Read timed out - in the link below). After troubleshooting, the root cause is Grouper WS is not very responsive or having a stale connection. Is there a way to fix below issue?



Note: There are no errors in the grouper_error.log file.   


Any guidance is truly appreciated.


Thank you,
