LDAP System Administration

Be extra effective and make your existence more uncomplicated. That's what LDAP method management is all about.

System directors usually spend loads of time handling configuration info positioned on many various machines: usernames, passwords, printer configurations, electronic mail purchaser configurations, and community filesystem configurations, to call a number of. LDAPv3 presents instruments for centralizing all the configuration info and putting it below your keep an eye on. instead of keeping numerous administrative databases (NIS, lively listing, Samba, and NFS configuration files), you may make alterations in just one position and feature your whole platforms instantly "see" the up to date information.

Practically platform self sufficient, this ebook makes use of the generally to be had, open resource OpenLDAP 2 listing server as a premise for examples, displaying you ways to exploit it that will help you deal with your configuration details successfully and securely. OpenLDAP 2 ships with such a lot Linux® distributions and Mac OS® X, and will be simply downloaded for many Unix-based platforms. After introducing the workings of a listing provider and the LDAP protocol, all points of establishing and fitting OpenLDAP, plus key ancillary programs like SASL and OpenSSL, this e-book discusses:

• Configuration and entry control
• allotted directories; replication and referral
• utilizing OpenLDAP to switch NIS
• utilizing OpenLDAP to control e mail configurations
• utilizing LDAP for abstraction with FTP and HTTP servers, Samba, and Radius
• Interoperating with diversified LDAP servers, together with energetic Directory
• Programming utilizing Net::LDAP

with a purpose to be a grasp of your area, LDAP approach management might help you wake up and operating speedy despite which LDAP model you utilize. After examining this publication, inspite of no prior LDAP event, you'll be ready to combine a listing server into crucial community prone resembling mail, DNS, HTTP, and SMB/CIFS.

In July 1999, the IEEE approved the 1000Base-T standard, which allows Gigabit Ethernet to run over Category 5 cable! 1 UTP cable UTP Cabling and the Need for Speed 13 Shielded Twisted Pair (STP) Shielded twisted-pair (STP) cabling was first made popular by IBM when it introduced Type classification for data cabling. Though more expensive to purchase and install than UTP, STP offers some distinct advantages. The current ANSI/TIA/EIA-568-B Cabling Standard recognizes IBM Type 1A horizontal cable, which supports frequency rates of up to 300MHz, but does not recommend it for new installations.

Limited Use The limited-use rating is for single and duplex (two-family) residences only. Some exceptions in the code allow its use in other environments, as in multitenant spaces such as apartments. However, the exceptions impose requirements that are typically either impractical or aesthetically unpleasant, and so it is better to consider limited-use cables as just for single and twofamily residences. Cable Jackets Because UTP is virtually ubiquitous in the LAN environment, the rest of this chapter will focus on design criteria and transmission-performance characteristics related to UTP cable.

1 Common Coaxial-Cable Types Cable Description RG-58 /U A 50-ohm coaxial cable with a solid core. Commonly called thinnet and used with 10Base-2 Ethernet and some cable TV applications. RG-58 A/U A 50-ohm coaxial cable with a stranded core. Also known as thinnet. Used by 10Base-2 Ethernet and some cable TV applications. RG-58 C/U A military-specification version of RG-58 A/U. RG-59U A 75-ohm coaxial cable. Used with Wang systems and some cable TV applications. RG-6U A 75-ohm coaxial cable. The current minimum grade to install in residences because it will handle the full frequency range of satellite service, plus highdefinition TV and cable-modem service.
