 +The document that I followed to install ldap and kerbrouce sugested that I setup log monitoring so that is thee first thing I did was:
  
 +cd /var/log; tail -F daemon.log user.log auth.log debug kern.log syslog dmesg messages kerberos/{krb5kdc,kadmin,krb5lib}.log
 +
 +My system was set up with three servers, one system where the ldap and Kerbrose Application was installed and two cleint systems:
 +
 +
 +  *vm14.student.lab Application server ip 10.88.3.14 
 +  *vm15.student.lab Client system    ip 10.88.3.15
 +  *vm16.student.lab          Client system  ip 10.88.3.16
 + 
 +
 +Next I needed to setup the host files on each system. \\
 +Host file for vm14:
 +
 +10.80.3.14       vm14.student.lab vm14 #ldap server \\
 +10.80.3.15      vm15.student.lab vm15  #client \\
 +10.80.3.16    vm16.student.lab vm16  #client 
 +
 +Host file for vm15:
 +
 + 10.80.3.14      vm14.student.lab  vm14 afs1     #ldap server \\
 + 10.80.3.15      vm15.student.lab  vm15  #client
 +
 +Host file for vm16:
 +
 + 10.80.3.14      vm14.student.lab vm14 afs1  #ldap server \\
 + 10.80.3.16      vm16.student.lab vm16  #client    
 +
 +Log on to vm14.student.lab \\
 +NOTE from this point on all entries will be shown in **Bold** and where you see //PASSWORD// enter a password of your choosing.
 +
 +====== Server installation ======
 +
 +The process that I followed sugested that the server compnent to install is called slapd
 +
 +apt-get install slapd ldap-utils
 +
 +Debconf answers for reference:\\
 +Omit OpenLDAP server configuration? **No**
 +
 +DNS domain name: **student.lab**
 +
 +Organization name? **student.lab**
 +
 +Administrator password: //PASSWORD//
 +
 +Confirm password: //PASSWORD//
 +
 +Database backend to use: **HDB**
 +
 +Do you want the database to be removed when slapd is purged? **No**
 +
 +Allow LDAPv2 protocol? **No**
 +
 +Enable the following two lines in /etc/ldap/ldap.conf, create the file if necessary:\\
 +
 +%%//BASE dc=student, dc=lab// %% \\
 +%%//URI ldap://10.80.3.14// %%
 +
 +====== Server Configuration ======
 +
 +Then, let's edit the server's configuration file in /etc/ldap/slapd.conf to tune its behavior. \\
 +Make sure all the schema files are enabled:
 +
 +**include /etc/ldap/schema/core.schema** \\
 +**include /etc/ldap/schema/cosine.schema** \\
 +**include /etc/ldap/schema/nis.schema** \\
 +**include /etc/ldap/schema/inetorgperson.schema** 
 +
 +Change the verbosity level from 0 or “none” to 256:
 +
 +**loglevel 256**
 +
 +Search for line “index objectClass eq” and add the second line below
 +
 +index objectClass eq \\
 +**index uid eq**
 +
 +To apply the new index option, run the following commands:
 +
 +**invoke-rc.d slapd stop** \\
 +**slapindex** \\
 +**chown -R openldap:openldap /var/lib/ldap** \\
 +**invoke-rc.d slapd start** \\
 +**Initial test using ldapsearch and slapcat**
 +
 +**ldapsearch -x**
 +

 +**Invoke-rc.d slapd stop** \\
 +**slapadd -c -v -l /var/tmp/ou.ldif** \\
 +**invoke-rc.d slapd start** 
 +
 +Next I use ldapsearch to verify the entries have been created.\\
 +**ldapsearch -x ou=people**
 +
 +# extended LDIF \\

 +# LDAPv3 \\

 +ou: People \\
 +objectClass: organizationalUnit
 +
 +# search result \\
 +search: 2 \\
 +result: 0 Success
 +
 +# numResponses: 2 \\
 +# numEntries: 1
 +
 +====== User Creation ======
 +
 +
 +Next I created a user accounts by editing: /var/tmp/user1.ldif
 +
 +**vi /var/tmp/user1.ldif**
 +
 +dn: cn=**mirko**,ou=group,dc=**student**,dc=**lab** \\
 +cn: **mirko** \\
 +gidNumber: **20000** \\
 +objectClass: top \\
 +objectClass: posixGroup
 +
 +dn: uid=**mirko**,ou=people,dc=**student**,dc=**lab** \\
 +uid: **mirko** \\
 +uidNumber: **20000** \\
 +gidNumber: **20000** \\
 +cn: **Mirko** \\
 +sn: **Mirko** \\
 +objectClass: top \\
 +objectClass: person \\
 +objectClass: posixAccount \\
 +objectClass: shadowAccount \\
 +loginShell: /bin/bash \\
 +homeDirectory: /home/**mirko** \\
 +
 +To load the LDIF file into the server: \\
 +
 +**ldapadd -c -x -D cn=admin,dc=student,dc=lab -W -f /var/tmp/user1.ldif ** \\
 +Enter LDAP Password: //PASSWORD//
 +
 +adding new entry “cn=mirko,ou=group,dc=student,dc=lab”
 +
 +adding new entry “uid=mirko,ou=people,dc=student,dc=lab”
 +
 +Now to define the new user's password: \\
 +**ldappasswd -x -D cn=admin,dc=student,dc=lab -W -S uid=mirko,ou=people,dc=student,dc=lab**
 +
 +New password: NEW USER //PASSWORD//
 +
 +Re-enter new password: NEW USER //PASSWORD//
 +
 +Enter LDAP Password: //ADMIN PASSWORD//
 +
 +next I verified that the account is setup. \\
 +**ldapsearch -x uid=mirko**
 +
 +# extended LDIF \\
 +# \\   
 +# LDAPv3 \\
 +# base <dc=student, dc=lab> (default) with scope subtree \\
 +# filter: uid=mirko \\
 +# requesting: ALL
 +#
 +
 +# mirko, people, student.lab \\
 +dn: uid=mirko,ou=people,dc=student,dc=lab \\
 +uid: mirko \\
 +uidNumber: 20000 \\
 +gidNumber: 20000 \\
 +cn: Mirko \\
 +sn: Mirko \\
 +objectClass: top \\
 +objectClass: person \\
 +objectClass: posixAccount \\
 +loginShell: /bin/bash \\
 +homeDirectory: /home/mirko 
 +
 +# search result \\ 
 +search: 2 \\
 +result: 0 Success
 +
 +# numResponses: 2 \\
 +# numEntries: 1
 +
 +====== NSS configuration ======
 +
 +
 +To enable the system see LDAP accounts, we need to install libnss-ldap \\
 +**apt-get install libnss-ldap nscd**
 +
 +LDAP server URI: %%ldap://%% **10.80.3.14 /** 
 +
 +Distinguished name of the search base: **dc=student,dc=lab**
 +
 +LDAP version to use: **3**
 +
 +Does the LDAP database require login? **No**
 +
 +Special LDAP privileges for root? **No** \\
 +Make the configuration file readable/writeable by its owner only? **No** \\
 +Allow LDAP admin account to behave like local root? **Yes**
 +
 +Make local root Database admin. **No**
 +
 +Does the LDAP database require login? **No**
 +
 +LDAP administrative account: **cn=admin,dc=h15,dc=ri**
 +
 +LDAP administrative password: //PASSWORD//
 +
 +Local crypt to use when changing passwords. **md5** 
 +
 +To configure the NSS module further:
 +
 +**vi /etc/libnss-ldap.conf**
 +
 +base **dc=student,dc=lab** \\
 +%%uri ldap://%% **10.80.3.14**
 +
 +Finally, to activate the LDAP NSS module:
 +
 +**vi /etc/nsswitch.conf**
 +
 +replacing the following two lines:
 +
 +passwd: **files ldap**\\
 +group: **files ldap**
 +
 +====== PAM configuration ======
 +
 +
 +The final step in this article pertains to integrating LDAP into the system authentication procedure. \\
 +Let's install and configure libpam-ldap. (You might have already done this step automatically, during libnss-ldap installation — in that case Debian will just report the package is already installed).
 +
 +**apt-get install libpam-ldap**
 +
 +Make local root Database admin. **No**
 +
 +Does the LDAP database require login? **No**
 +
 +Local crypt to use when changing passwords. **md5**
 +
 +To configure the PAM module:
 +
 +**vi /etc/pam_ldap.conf.**
 +
 +base **dc=student,dc=lab**
 +%%uri ldap: //%%**10.80.3.14** \\
 +
 +**vi /etc/pam.d/common-account** \\
 +need to make sure these line are included
 +
 +**account sufficient pam_unix.so** \\
 +**account required pam_ldap.so**
 +
 +# Enable if using Kerberos: #account required pam_krb5.so
 +
 +**vi /etc/pam.d/common-auth**
 +
 +need to make sure these line are included
 +
 +# Disable the three lines if using Kerberos:  \\
 +**auth [success=1 default=ignore] pam_unix.so nullok_secure**
 +**auth required pam_ldap.so use_first_pass**
 +**auth required pam_permit.so**
 +
 +# Enable the three lines if using Kerberos:
 +#auth sufficient pam_unix.so nullok_secure
 +#auth sufficient pam_krb5.so use_first_pass
 +#auth required pam_deny.so
 +
 +**vi /etc/pam.d/common-password**
 +
 +need to make sure these lines are included
 +
 +password sufficient pam_unix.so nullok obscure md5
 +
 +#Disable if using Kerberos:
 +#password required pam_ldap.so use_first_pass
 +
 +#Enable if using Kerberos:
 +password required pam_krb5.so use_first_pass
 +/etc/pam.d/common-session
 +session required pam_unix.so
 +session required pam_mkhomedir.so skel=/etc/skel/ umask=0022
 +
 +# Enable if using Kerberos:
 +session optional pam_krb5.so minimum_uid=1000
 +
 +
 +====== Client Configuration ======
 + 
 +
 +These commands need to run on both clients\\
 +**apt_get install pam_ldap libnss_ldap** \\
 +**apt-get install pam_ldap libnss_ldap** \\
 +**apt-get install pam-ldap libnss-ldap** \\
 +**apt-get install libpam-ldap**
 +
 +After that to save time and reduce typos I scp these files over to vm15 and vm16 from vm14
 +
 +/etc/nsswitch.conf \\
 +/etc/pam.d/common-account\\
 +/etc/pam.d/ common-auth \\
 +/etc/pam.d/common-password \\
 +/etc/pam.d/common-session
 +
 +log in to vm14 and do a:
 + 
 +scp /etc/pam.d/common* root@vm15.student.lab \\
 +scp /etc/pam.d/common* root@vm16.student.lab
 +
 +This finishes the LDAP install next comes the Kerberos install.
