OK, this has been asked before and here, but none of the answers are working for me, so I'm asking again....

My username is tullyc, and according to groups I have permissions for the tomcat group.

$ groups
tullyc tomcat

and id agrees:

$ id
uid=1005(tullyc) gid=1005(tullyc) groups=1005(tullyc),1003(tomcat)
$ id -a
uid=1005(tullyc) gid=1005(tullyc) groups=1005(tullyc),1003(tomcat)

but, I still cannot create directories!

$ ls -al /usr/share/tomcat9-root/webapps/
total 45128
drwxr-x--- 4 tomcat tomcat 4096 Jun 14 20:10 .
drwxrwxr-x 7 tomcat tomcat 4096 Jun 14 21:08 ..
-rw-r--r-- 1 tullyc tullyc 46192111 Jun 14 20:10 radar.war
drwxr-xr-x 2 root root 4096 Jun 14 15:27 radar_data
drwxr-xr-x 3 tullyc tullyc 4096 Jun 14 15:28 radarui

Based on the directory listing, and output from groups and id this should work:

$ mkdir /usr/share/tomcat9-root/webapps/radar
mkdir: cannot create directory '/usr/share/tomcat9-root/webapps/radar': Permission denied

I initially tried just exiting my ssh session and starting a new one but still got permission denied. So, I took the sledgehammer approach (this is not my production server so I can reboot at will) and rebooted. Even after a reboot I still get the same answers from groups and id and still get permission denied.

I am puzzled because I was previously able to create files and directories in the /usr/share/tomcat9-root/webapps directory after setting it's owner and group to tomcat:tomcat.

So, having both logged out and logged back in and even rebooted the server, and showing that I have the proper groups and permissions, why can't I create files or directories?

  Perhaps try newgrp tomcat before creating the directory?
