Description Kaushik Banerjee 2014-10-16 06:40:06 UTC 
Description of problem:
service lookups returned in lowercase with case_sensitive=preserving

Version-Release number of selected component (if applicable):
sssd-1.12.1-3.el7

How reproducible:
Always

Steps to Reproduce:
1.
dn: cn=Svc1,ou=Services,dc=example,dc=com
objectClass: ipService
cn: svc1_alias1
cn: SVC1_Alias2
cn: Svc1
ipServicePort: 65535
ipServiceProtocol: Tcp
ipServiceProtocol: udp
ipServiceProtocol: dummy_proto

2. Configure and start sssd with case_sensitive=preserving

3. Lookup service

Actual results:
# getent services Svc1
svc1                  65535/tcp svc1_alias1 svc1_alias2

# getent services 65535/TCP
svc1                  65535/tcp svc1_alias1 svc1_alias2

Expected results:
Case should not be lowered

Comment 5 Kaushik Banerjee 2014-11-04 12:17:54 UTC 
Only the name of the service has it's case preserved. The protocol name and aliases are still lowercased.

On testing with sssd-1.12.2-7.el7, I get:
# getent services SVC1
Svc1       65535/tcp svc1_alias1 svc1_alias2

Michal would explain better, but I'm afraid this is a limitation that we can't work around if we want to keep the case-insensitive /matching/.

Can we take this as a current design limitation and file a (deferred) ticket to also keep the case of services and protocols in case a customer or a user is also interested in this functionality?

We can also document this shortcoming in the man pages.

I missed that this bugzilla had new comments, so sorry for delayed answer. Jakub is right, we can not preserve the alias and protocol names without loosing case-insensitivity. The upstream man page was already updated to mention this.
Comment 8 Kaushik Banerjee 2014-12-03 10:18:46 UTC 
Verified in version 1.12.2-28.el7

# getent services svc1
Svc1                  65535/tcp svc1_alias1 svc1_alias2

# getent services 65535/TCP
Svc1                  65535/TCP svc1_alias1 svc1_alias2
