DBCA Failed with CRS-2566: User 'oracle' does not have sufficient permissions to operate on resource 'ora.driver.afd'

DBCA 12.2.0.1 failed with following errors 

   PRCR-1006: Failed to add resource ora.corcl.db for corcl
   PRCR-1071: Failed to register or update resource ora.corcl.db
   CRS-2566 : User 'oracle' does not have sufficient permissions to operate on resource 'ora.driver.afd', which is part of the dependency specification.

The clusterware is Grid Infrastructure 18c in Standalone mode (Oracle Restart), the GI home owner is grid. Log into system as grid and check the permissions of CRS resourc 'ora.driver.afd'
[grid@host01]$ crsctl stat res ora.driver.afd -p -attr ACL
NAME=ora.driver.afd
ACL=owner:grid:rwx,pgrp:asmadmin:r-x,other::r--,user:grid:r-x

ACL shows that grid is the owner of the resource and have full control (rwx) on the resource, OS group asmadmin has read & execute(r-x), and database owner oracle is not explicitly granted permissions on this resource.  

Check if oracle is member of group asmadmin,
[grid@host01]$ id oracle
uid=104(oracle) gid=112(oinstall) groups=112(oinstall),114(asmdba),116(dba),117(oper),118(racdba),119(backupdba),120(dgdba),121(kmdba)

User oracle is not in the group asmadmin. Therefore, DBCA is telling the truth that oracle does not have permissions on the resource. It is technically easy to fix this issue, but honestly it is not expected there and should be considered as GI 18c bug.

To fix it, just add the group of which oracle is a member (I pick oinstall) to the ACL as following,
[grid@host01]$ crsctl modify resource ora.driver.afd -attr "ACL='owner:grid:rwx,pgrp:asmadmin:r-x,other::r--,group:oinstall:r-x,user:grid:r-x'" -init

Confirm that the ACL is changed,
[grid@host01]$ crsctl stat res ora.driver.afd -p -attr ACL
NAME=ora.driver.afd
ACL=owner:grid:rwx,pgrp:asmadmin:r-x,other::r--,group:oinstall:r-x,user:grid:r-x'

Now, DBCA can create database successfully.
