Likewise Open Installation and Administration Guide - Purple Rage

4.2. Requirements for the Agent
This section lists requirements for installing and running the Likewise agent. Requirements for the Likewise Management Console, which is part of
Likewise Enterprise and the UID-GID module, are detailed in the chapter on installing the console. Likewise Open does not include the Likewise
Management Console.
Before you install the Likewise agent, make sure that the following environmental variables are not set: LD_LIBRARY_PATH, LIBPATH, SHLIB_PATH,
LD_PRELOAD. Setting any of these environmental variables violates best practices for managing Unix and Linux computers because it causes Likewise
to use non-Likewise libraries for its services. For more information on best practices, see http://linuxmafia.com/faq/Admin/ld-lib-path.html. Likewise does
not support installations that use these environmental variables. If joining the domain fails with an error message that one of these environmental
variables is set, stop all the Likewise daemons, clear the environmental variable, make sure it is not automatically set when the computer restarts, and
then try to join the domain again.
If you must set LD_LIBRARY_PATH, LIBPATH, or SHLIB_PATH for another program, put the Likewise library path (/opt/likewise/lib
or /opt/likewise/lib64) before any other path -- but keep in mind that doing so may result in side effects for your other programs, as they will now
use Likewise libraries for their services.
Patch Requirements
It is recommended that you apply the latest patches for your operating system before you install Likewise. Known patch requirements are listed below.
Sun Solaris
All Solaris versions require the md5sum utility, which can be found on the companion CD.
Sun Solaris 10 requires update 5 or later. The Solaris 10 05/08 (or later) patch bundle is available at http://sunsolve.sun.com/. Solaris 10_x86 requires
the patch for nscd, either patch ID number 138047-02 or the patch that supercedes it, number 138264-02. This patch available for SPARC as patch
138046.
Solaris 8 Sparc should be fully patched according to Sun's recommendations. Likewise depends on the latest patch for libuuid. On Sparc systems,
the patch for libuuid is 115831. Sun patch 110934-28 for Solaris 5.8 is also required for Solaris 8.
Solaris 8 Intel systems also require the latest patch for libuuid: 115832-01. Sun patches 110403-06 and 110935-26 are also required. Patch 110403-
06 must be installed before you install patch 110935-26.
Solaris 9 requires Sun patch 113713-28 for Solaris 5.9.
OpenSolaris is compatible with Likewise without any patches.
HP-UX
Secure Shell: For all HP-UX platforms, it is recommended that a recent version of HP's Secure Shell be installed. Likewise recommends that you use
HP-UX Secure Shell A.05.00.014 or later.
Sudo: By default, the versions of sudo available from the HP-UX Porting Center do not include the Pluggable Authentication Module, or PAM, which
Likewise requires to allow domain users to execute sudo commands with super-user credentials. It is recommended that you download sudo from the
HP-UX Porting Center and make sure that you use the with-pam configuration option when you build it.
HP-UX 11iv1 requires the following patches: PHCO_36229, PHSS_35381, PHKL_34805, PHCO_31923, PHCO_31903, and PHKL_29243. Although
these patches may be superceded by subsequent patches, these patches represent the minimum patch level for proper operation.
Kerberos client libraries: For single sign-on with HP-UX 11.11 and 11.23, you must download and install the latest KRB5-Client libraries from the HP
Software Depot. (By default, HP-UX 11.31 includes the libraries.)
Other Requirements for the Agent
AIX
On AIX computers, PAM must be enabled. LAM is supported only on AIX 5.x. PAM must be used exclusively on AIX 6.x.
Secure Shell
To properly process logon events with Likewise, your SSH server or client must support the UsePam yes option. For single sign-on, both the SSH
server and the SSH client must support GSSAPI authentication.
Other Software
Telnet, rsh, rcp, rlogin, and other programs that uses PAM for processing authentication requests are compatible with Likewise.
Networking Requirements
Each Unix, Linux, or Mac computer must have fully routed network connectivity to all the domain controllers that service the computer's Active Directory
site. Each computer must be able to resolve A, PTR, and SRV records for the Active Directory domain, including at least the following:
A domain.tld
SRV _kerberos._tcp.domain.tld
SRV _ldap._tcp.domain.tld
SRV _kerberos._udp.sitename.Sites._msdcs.domain.tld
A domaincontroller.domain.tld
In addition, several ports must be open; see Make Sure Outbound Ports Are Open.
Disk Space Requirements
The Likewise agent requires 100 MB of disk space in the /opt mount point. The agent also creates configuration files in /etc/likewise and offline
