Unix installation and join
Note: For more details on installing and joining the Safeguard Authentication Services client, please see the Safeguard Authentication Services Administration Guide. Commands prefixed with $ must be run by the SAP instance owner account. Commands prefixed with # must be run by root.
To install the Safeguard Authentication Services client and join the Unix system to Active Directory
- Mount the product media or extract the product archive, and change directory to the base directory. For example:
# mount /mnt/cdrom; cd /mnt/cdrom
- Run the preflight program to check for proper connectivity and patch requirements. If failures are reported, see the Safeguard Authentication Services Administration Guide for requirements and troubleshooting instructions.
# ./preflight example.com
Replace example.com with your Active Directory domain name.
- Install the Safeguard Authentication Services client.
# ./install.sh vasclnt
- Join the system to Active Directory.
# /opt/quest/bin/vastool -u Administrator join --skip-config example.com
Where Administrator is an Active Directory user with rights to join and example.com is your Active Directory domain name.
Note: Ignore any license warnings reported from the join process. These are not relevant to SSO for SAP.
Unix configuration
To configure the SAP server on Unix to use Single Sign-on for SAP
- Change the group ownership and permissions of the host.keytab file.

- List the keytab and note the Principal name containing a $.
$ /opt/quest/bin/vastool ktutil list /etc/opt/quest/vas/host.keytab: Vno Type Principal 2 aes128-cts-hmac-sha1-96 host/alvlabu22.example.com@EXAMPLE.COM 2 aes128-cts-hmac-sha1-96 ALVLABU22$@EXAMPLE.COM 2 aes128-cts-hmac-sha1-96 cifs/alvlabu22.example.com@EXAMPLE.COM 2 aes128-cts-hmac-sha1-96 host/ALVLABU22@EXAMPLE.COM 2 aes256-cts-hmac-sha1-96 host/alvlabu22.example.com@EXAMPLE.COM 2 aes256-cts-hmac-sha1-96 ALVLABU22$@EXAMPLE.COM 2 aes256-cts-hmac-sha1-96 cifs/alvlabu22.example.com@EXAMPLE.COM 2 aes256-cts-hmac-sha1-96 host/ALVLABU22@EXAMPLE.COM 2 arcfour-hmac-md5 host/alvlabu22.example.com@EXAMPLE.COM 2 arcfour-hmac-md5 ALVLABU22$@EXAMPLE.COM <-- Take note of this $ name to use in the next step. 2 arcfour-hmac-md5 cifs/alvlabu22.example.com@EXAMPLE.COM 2 arcfour-hmac-md5 host/ALVLABU22@EXAMPLE.COM
