In 16084:

refs #12995

• improved utf8 handling.

Some notes:

1. only lower case DNs will work:

wrong:
dir_basedn = OU=Энергомаш,DC=foo,DC=bar
correct:
dir_basedn = OU=энергомаш,DC=foo,DC=bar

2. group_expand = 1 will lead to "Genshi UnicodeDecodeError..." if invoking "​http://host/trac/admin/general/perm" since the trac templates do not handle unicode correctly.

refs #12995

• added a way to avoid the ""Genshi UnicodeDecodeError..."

My tests is successful. Working with capital chars in dir_basedn
