Install Kerberos in OSX
To start to use Single-sign On (SSO) in Mac environments we need install the Kerberos/Seclude library in
our system.
If you don’t have installed , you can download from :
ftp://ftp.sap.com/pub/sapgui/java/misc/SNC_Krb5_SECUDE-MacOSX.tar

(control the forum https://www.sdn.sap.com/irj/sdn/message?messageID=2202442 for updates)
This TAR file have 2 files

• sncgssec.dyld for PowerPC (Secude framework must already be installed!)

• sncgssk5.dyld for Universal

Select the better library for you and rename to sncgss.dyld , then copy to “/usr/local/lib” or “/usr/lib” directory.
If you want use another directory, you have to set the SNC_LIB environment variable to the location of the
library.
i.e. export SNC_LIB=/mnt/server/lib/sncgss.dyld (for bash)
or set the user environment via file quot;~/.MacOSX/environment.plistquot; (see Developer Connection Technical
QA 1067 and Property List Editor Application which comes with the Developer Tools)

Configure Kerberos
If you work like consultant, usually you don’t include your MAC in the client domain, for use SSO you only
need type your password the first time when you logon, and then you have SSO until the ticket expire.
You need to setup the krb5.conf file in /etc with the follow lines :
[logging]
default = FILE:/var/log/krb5libs.log
kdc = FILE:/var/log/krb5kdc.log
admin_server = FILE:/var/log/kadmind.log

[libdefaults]
ticket_lifetime = 24000
default_realm = SUB.DOMAIN.NET
default_tkt_enctypes = des-cbc-crc des-cbc-md5
default_tgs_enctypes = des-cbc-crc des-cbc-md5

[realms]
SUB.DOMAIN.NET = {
kdc = server_hostname.sub.domain.net
admin_server = server_hostname.sub.domain.net
default_domain = sub.domain.net
}

[domain_realm]
.sub.domain. = SUB.DOMAIN.NET
server_hostname.sub.domain.net = SUB.DOMAIN.NET

Configure Sap Logon
First of all, you need to configure your SAP Logon, in this example we configure the guimsg.txt in the
preference panel with file:/Library/Preferences/SAP/guimsg.txt,
The content of guimsg.txt is:
ELD : /M/server_hostname/S/3601

Click in New

Click in the drop box of System and select ELD

The SAPGUI show the Group/Servers for Load balance, select the right option and click Security

In the Security TAB you see the SNC Name of the server, click in “Enable Secure Network Communication”
and Save.

When you try to logon, the system ask your DOMAIN password
