Hi all,
I found a solution for my environment:
- Clear all entries for the failing postmaster account in the database from table auth_token:
Delete using the SQL query: DELETE FROM public.auth_token WHERE account_id=’X‘;
- Secondly edit some entries in the file „/opt/otobo/Kernel/System/OAuth.pm“:
Line 183/184 shows:
my $SQL = "SELECT token FROM $Self->{TokenTable} WHERE "
. "account_type = LOWER(?) AND account_id = ? AND token_type = 'refresh'";Adapt the lines to:
my $SQL = "SELECT token FROM $Self->{TokenTable} WHERE "
. "account_type = ? AND account_id = ? AND token_type = 'refresh'";Line 256/257 shows:
SQL => "DELETE FROM $Self->{TokenTable} WHERE "
. "account_type = LOWER(?) AND account_id = ? AND token_type = 'refresh'",Adapt the lines to:
SQL => "DELETE FROM $Self->{TokenTable} WHERE "
. "account_type = ? AND account_id = ? AND token_type = 'refresh'",- Once the changes are done. Authenticate the postmaster mail account again and follow up if mail fetch continues to work.
It looks like the refresh token is not being updated on new logins and not being found when searching for because of the „LOWER()“ function in the SQL queries.
Hope this helps you guys too.
KR,
Fred
