That link is for a 2013 discussion, is there any more current discussion. We are currently running Guac v1.0.0 on a Cent OS 7 Virtual machine (ESXI6.7) with 4 processors 8 Gig ram and a 100 gb hard drive. We currently have 32 simultaneous users (Just checked “currently logged on”) our resources are sitting at 940MHz CPU – 409 MB memory and 50.8 GB hard drive.
Our current system consists of the Guac system and 30 installed and running Win 7 desktops on one server and a “sister” server that holds about 40 more virtual Win 7 desktops. Along with the virtual users, who connect from all over the world, we have about 30 “potential” users that occasionally connect through Guacamole to their physical Windows 10 systems here in the local office. All of our users log into their virtual desktops to run an IBM ACS green screen emulator for data entry into an IBM Power system. As well as running Chrome on their virtual desktops for data lookup. We have been asked to increase our setup by “up to” 100 more users. I am hoping that we can get away with just adding drive space and memory to the “sister” server. As the OP was wondering how many simultaneous users you can run, I also would like to know if we will need to set up a second Guac server to accomplish our required task.

Exercise caution when opening attachments or clicking links, especially from unknown senders. Hi, I was wondering if anyone could provide some insight on this issue. To recap my previous message I have a ldap-user-search-filter set to (&(objectClass=person)(memberof=cn=guacusers,ou=groups,dc=asrc,dc=crossroads)) however any valid LDAP user is allowed to login on the Guacamole web page. My configuration: Guacamole 1.1.0, Ubuntu 18.04, openLDAP (libldap-2.4-2:amd64) on a separate Ubuntu 18.04 VM. since my first message I’ve done some additional investigation into the problem. By looking at the logs on my LDAP server I can see that the filters are passed on to the LDAP server and they do return the correct number of entries. There are a couple of things that seem strange to me: * Not sure why the "(|(uid=*)) clause is added to the main group filter defined in my configuration * For the user in the guacusers group the SeeAlso seems to expand to all the object of class groupOfNames in my directory Here are the log entries for the user that is in the guacusers group: slapd[904]: conn=9470 fd=48 ACCEPT from IP=10.16.33.12:52422 (IP=0.0.0.0:389) slapd[904]: conn=9470 op=0 BIND dn="uid=user_in_guacusers,ou=users,dc=my,dc=domain" method=128 slapd[904]: conn=9470 op=0 BIND dn="uid=user_in_guacusers,ou=users,dc=my,dc=domain" mech=SIMPLE ssf=0 slapd[904]: conn=9470 op=0 RESULT tag=97 err=0 text= slapd[904]: conn=9470 op=1 SRCH base="ou=groups,dc=my,dc=domain" scope=2 deref=0 filter="(&(!(objectClass=guacConfigGroup))(|(member=uid=user_in_guacusers,ou=users,dc=my,dc=domain)))" slapd[904]: conn=9470 op=1 SEARCH RESULT tag=101 err=0 nentries=5 text= slapd[904]: conn=9470 fd=48 closed (connection lost) slapd[904]: conn=9471 fd=48 ACCEPT from IP=10.16.33.12:52424 (IP=0.0.0.0:389) slapd[904]: conn=9471 op=0 BIND dn="uid=user_in_guacusers,ou=users,dc=my,dc=domain" method=128 slapd[904]: conn=9471 op=0 BIND dn="uid=user_in_guacusers,ou=users,dc=my,dc=domain" mech=SIMPLE ssf=0 slapd[904]: conn=9471 op=0 RESULT tag=97 err=0 text= slapd[904]: conn=9471 op=1 SRCH base="ou=users,dc=my,dc=domain" scope=2 deref=0 filter="(&(&(objectClass=person)(memberOf=cn=guacusers,ou=groups,dc=my,dc=domain))(|(uid=*)))" slapd[904]: conn=9471 op=1 SEARCH RESULT tag=101 err=0 nentries=6 text= slapd[904]: conn=9471 op=2 SRCH base="ou=groups,dc=my,dc=domain" scope=2 deref=0 filter="(&(!(objectClass=guacConfigGroup))(|(cn=*)))" slapd[904]: conn=9471 op=2 SEARCH RESULT tag=101 err=0 nentries=46 text= slapd[904]: conn=9471 op=3 SRCH base="ou=groups,dc=my,dc=domain" scope=2 deref=0 filter="(&(!(objectClass=guacConfigGroup))(|(member=uid=user_in_guacusers,ou=users,dc=my,dc=domain)))" slapd[904]: conn=9471 op=3 SEARCH RESULT tag=101 err=0 nentries=5 text= slapd[904]: conn=9471 op=4 SRCH base="ou=guac_config,dc=my,dc=domain" scope=2 deref=0 filter="(&(objectClass=guacConfigGroup)(|(member=uid=user_in_guacusers,ou=users,dc=my,dc=domain)(seeAlso=cn=group1,ou=groups,dc=my,dc=domain)(seeAlso=cn=group2,ou=groups,dc=my,dc=domain)(seeAlso=cn=group3,ou=groups,dc=my,dc=domain)(seeAlso=cn=group4,ou=groups,dc=my,dc=domain)(seeAlso=cn=guacusers,ou=groups,dc=my,dc=domain)))" slapd[904]: conn=9471 op=4 SEARCH RESULT tag=101 err=0 nentries=1 text= And for the user that is not in the guacusers group: slapd[904]: conn=9478 fd=88 ACCEPT from IP=10.16.33.12:52430 (IP=0.0.0.0:389) slapd[904]: conn=9478 op=0 BIND dn="uid=user_not_in_guacusers,ou=users,dc=my,dc=domain" method=128 slapd[904]: conn=9478 op=0 BIND dn="uid=user_not_in_guacusers,ou=users,dc=my,dc=domain" mech=SIMPLE ssf=0 slapd[904]: conn=9478 op=0 RESULT tag=97 err=0 text= slapd[904]: conn=9478 op=1 SRCH base="ou=groups,dc=my,dc=domain" scope=2 deref=0 filter="(&(!(objectClass=guacConfigGroup))(|(member=uid=user_not_in_guacusers,ou=users,dc=my,dc=domain)))" slapd[904]: conn=9478 op=1 SEARCH RESULT tag=101 err=0 nentries=0 text= slapd[904]: conn=9478 fd=88 closed (connection lost) slapd[904]: conn=9479 fd=88 ACCEPT from IP=10.16.33.12:52432 (IP=0.0.0.0:389) slapd[904]: conn=9479 op=0 BIND dn="uid=user_not_in_guacusers,ou=users,dc=my,dc=domain" method=128 slapd[904]: conn=9479 op=0 BIND dn="uid=user_not_in_guacusers,ou=users,dc=my,dc=domain" mech=SIMPLE ssf=0 slapd[904]: conn=9479 op=0 RESULT tag=97 err=0 text= slapd[904]: conn=9479 op=1 SRCH base="ou=users,dc=my,dc=domain" scope=2 deref=0 filter="(&(&(objectClass=person)(memberOf=cn=guacusers,ou=groups,dc=my,dc=domain))(|(uid=*)))" slapd[904]: conn=9479 op=1 SEARCH RESULT tag=101 err=0 nentries=6 text= slapd[904]: conn=9479 op=2 SRCH base="ou=groups,dc=my,dc=domain" scope=2 deref=0 filter="(&(!(objectClass=guacConfigGroup))(|(cn=*)))" slapd[904]: conn=9479 op=2 SEARCH RESULT tag=101 err=0 nentries=46 text= slapd[904]: conn=9479 op=3 SRCH base="ou=groups,dc=my,dc=domain" scope=2 deref=0 filter="(&(!(objectClass=guacConfigGroup))(|(member=uid=user_not_in_guacusers,ou=users,dc=my,dc=domain)))" slapd[904]: conn=9479 op=3 SEARCH RESULT tag=101 err=0 nentries=0 text= slapd[904]: conn=9479 op=4 SRCH base="ou=guac_config,dc=my,dc=domain" scope=2 deref=0 filter="(&(objectClass=guacConfigGroup)(|(member=uid=user_not_in_guacusers,ou=users,dc=my,dc=domain)))" slapd[904]: conn=9479 op=4 SEARCH RESULT tag=101 err=0 nentries=0 text= And this is my full configuration file: #

I have the LDAP extension installed (along with the MySQL one) and I’ve defined connections directly into LDAP. Everything works just fine, users are authenticated and are allowed the proper connections, however I would like to allow only users MemberOf a one LDAP group (e.g. guacusers) to login to my Guacamole site. I’m using ldap-user-search-filter, but it does not seem to work. As of now any active users in my LDAP directory can login into the Guacamole site. No connections are displayed for the users that I would like to disallow, but nevertheless they can still login...

Note that if I run the same filter on my LDAP server, e.g.: ldapsearch -x -LLL -H ldap:/// -b "ou=users,dc=my,dc=domain" -s sub "(memberof=cn=guacusers,ou=groups,dc=my,dc=domain)” I get the expected result…. I’ve also tried adding other specifiers to the filter, like (memberof=cn=guacusers,ou=groups,dc=my,dc=domain) they all work when I query the LDAP server with ldapsearch, but don’t seem to have any effect when I use them in Guacamole.
