Update on this. It seems [e-mail] can’t read required attributes
from sudoers and that causes the problem. Do I need to modify LDAP
permissions somehow to enable reading of the required attributes? Example
of search with missing attributes below.

[root@dc1 ~]# kinit 'DC1$@TEEMU.LOCAL' -k -t /etc/krb5.sssd.keytab
[root@dc1 ~]# klist
Ticket cache: FILE:/tmp/krb5cc_0
Default principal: DC1$@TEEMU.LOCAL

[root@dc1 ~]# ldapsearch  -h dc1 -Y GSSAPI -b ou=Sudoers,dc=teemu,dc=local
