What do I need to get rid of Permission denied error on Linux?

I have tomcat installed in /opt/tomcat and would like to get access to sub-folders for user 'mck'.

mck@hp15-pc:/opt/tomcat$ ls bin
ls: cannot open directory 'bin': Permission denied

mck@hp15-pc:/opt/tomcat$

here are the permissions for /opt/tomcat

drwxr-xr-x 9 tomcat tomcat 4.0K 2020-12-23 21:30:41 ./
drwxr-xr-x 4 root   root   4.0K 2020-12-23 21:25:41 ../

I have added 'mck' user to 'tomcat' group here are the groups for 'mck'

mck@hp15-pc:/opt/tomcat$ groups mck
mck : mck tomcat

I noticed this strange output of 'id', I do not see the group 'tomcat' in the groups list if I omit the username.

mck@hp15-pc:~$ id
uid=1000(mck) gid=1000(mck) groups=1000(mck),4(adm),24(cdrom),27(sudo),30(dip),46(plugdev),114(lpadmin),134(sambashare)

mck@hp15-pc:~$ id mck
uid=1000(mck) gid=1000(mck) groups=1000(mck),4(adm),24(cdrom),27(sudo),30(dip),46(plugdev),114(lpadmin),134(sambashare),1002(tomcat)

I do not want to change the permissions or user and groups on the tomcat folder '/opt/tomcat'.

What do I need to do to allow access to subfolders of /opt/tomcat for user 'mck'? Is it possible?

I first tried logout and re-login but it did not resolve the issue.

I had to restart the system for the issue to go away.

Also, now the "id" and "id mck" both show identical output.

You need to change tomcat folder permission to mck user. i,e

chown -R mck.tomcat /opt/tomcat/
