4.6.2.3.4 Verify Domain Membership

The XenDesktop Controller requires that all VDA machines, whether Windows and Linux, have a

computer object in Active Directory. To verify that a Quest-joined Linux machine is on the domain:

sudo /opt/quest/bin/vastool info domain

If the machine is joined to a domain this will return the domain name. If not joined, you will see the

following error:

ERROR: No domain could be found.

ERROR: VAS_ERR_CONFIG: at ctx.c:414 in _ctx_init_default_realm

default_realm not configured in vas.conf. Computer may not be joined to

domain

4.6.2.3.5 Verify User Authentication

To verify that the Quest can authenticate domain users using PAM, logon with a domain user

account that has not logged onto the machine previously.

ssh localhost -l domain\\username

id -u

Check that a corresponding Kerberos credential cache file was created for the uid returned by the

id -u command:

ls /tmp/krb5cc_uid

Check that the tickets in user’s Kerberos credential cache are valid and not expired:

/opt/quest/bin/vastool klist

Exit the session:

exit

A similar test can be performed by logging on via Gnome Display Manager.

4.7 Add Linux Machine to Machine Catalog

The process for creating machine catalogs and adding Linux VDA machines is very similar to the

traditional Windows VDA approach. Refer to the online Citrix Product documentation for a more

complete description of how to complete these tasks.

For creating machine catalogs that contain Linux VDA machines, there are a few restrictions that

differentiates the process from creating machine catalogs for Windows VDA machines:

 For operating system, select Window Server OS. Citrix Studio does not yet support the

notion of a "Linux OS"; however, selecting Windows Server OS here implies an equivalent

shared desktops delivery model. The Windows Desktop OS option implies a single user

per machine delivery model, which is not applicable to Linux VDAs. Even for "Desktop"

Linux distributions, Windows Server OS must be selected.

 Ensure machines are set as not power managed.

 As PVS and MCS are not supported for Linux VDAs, choose the Another service or

technology (existing images) deployment method.
