Edit /etc/php.ini and make sure memory_limit is set to at least 32 MB:
memory_limit = 32M Last I checked, the version of phpldapadmin available via yum is broken, so we'll get the latest & extract it: Go To
Browse phpLDAPadmin Files on SourceForge.net & download the latest version. In my case that resulted in the following commands, your package may be newer:
mkdir /var/www/html/samba && cd /var/www/html/samba
wget
Download phpLDAPadmin from SourceForge.net
tar zxf phpldapadmin-1.1.0.7.tar.gz
ln -s phpldapadmin-1.1.0.7 pla
cp pla/config/config.php.example pla/config/config.php
Now edit ./pla/config/config.php and uncommment the following line:
$config->custom->jpeg['tmpdir'] = "/tmp";
Make newly setup software available
service httpd restart
chkconfig httpd on
Edit /etc/sysconfig/iptables and copy & modify line about ssh (--dport 22 -j ACCEPT), and right after it, add (assuming your CentOS install produced the default iptables file):
#Allow Https://
-A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 443 -j ACCEPT
#Allow samba:
-A RH-Firewall-1-INPUT -m multiport -p udp --dport 137,138 -j ACCEPT
-A RH-Firewall-1-INPUT -m state --state NEW -m multiport -p tcp --dport 139,445 -j ACCEPT
Now open your webbrowser and visit
https://192.168.0.5/samba/pla/ and login with Username
cn=root,dc=DOMAINNAME & your password. You should be able to look around and see some junk.
Integrate ldap and Samba
mv /etc/samba/smb.conf /etc/samba/smb.conf.dist
cp /usr/share/doc/smbldap-tools-0.9.5/smb.conf /etc/samba/smb.conf
Edit /etc/samba/smb.conf to your likings, the default ldap part should be fine.
Under [global], you will need to add these two settings not there by default:
nt acl support = yes
socket options = TCP_NODELAY SO_RCVBUF=8192 SO_SNDBUF=8192 SO_KEEPALIVE
cp /usr/share/doc/smbldap-tools-0.9.5/smbldap.conf /etc/smbldap-tools/smbldap.conf
net getlocalsid
Note,
net getlocalsid will error a bunch until the end, because you haven't fully configured samba yet -- but will produce the sid you need for the next step.
Edit /etc/smbldap-tools/smbldap.conf and insert
sid, domain, etc, all throughout the file till the end.
Edit /etc/smbldap-tools/smbldap_bind.conf and change both applicable lines, change "secret" to your password.
chmod 644 /etc/smbldap-tools/smbldap.conf
chmod 600 /etc/smbldap-tools/smbldap_bind.conf
authconfig-tui
Check that the output from authconfig-tui contains:
[ ] Local authorization is sufficient Now test your samba config:
testparm
smbpasswd -w YOUR_ROOT_LDAP_PASS_HERE
smbldap-populate
smbldap-populate will ask for the password, enter it.
Start the LDAP Samba installation up
/etc/init.d/smb start
chkconfig smb on
Add users/groups, correlate between unix and ldap:
useradd user1
smbldap-useradd -a -G 'Domain Users' -m -s /bin/bash -d /home/user2 -F "" -P user1
Get a picture of the UNIX groups that aren't there yet that LDAP assumes:
net groupmap list
Output is something like:
Domain Admins (S-1-5-21-990788473-1556064292-4137819756-512) -> domain_admins
Domain Users (S-1-5-21-990788473-1556064292-4137819756-513) -> domain_users
Domain Guests (S-1-5-21-990788473-1556064292-4137819756-514) -> 514
Domain Computers (S-1-5-21-990788473-1556064292-4137819756-515) -> 515
Administrators (S-1-5-32-544) -> 544
Account Operators (S-1-5-32-548) -> 548
Print Operators (S-1-5-32-550) -> 550
Backup Operators (S-1-5-32-551) -> 551
Replicators (S-1-5-32-552) -> 552
Add correlating groups to unix, using the suggested GIDs:
groupadd -g 514 samba_domain_guests
groupadd -g 515 samba_domain_computers
groupadd -g 544 samba_administrator
groupadd -g 548 samba_account_operators
groupadd -g 550 samba_print_operators
groupadd -g 551 samba_backup_operators
groupadd -g 552 samba_replicators
If you want to add a non-built-in group to LDAP/Samba, say for controlling which users can write/read files on a share, and have it determine that by groups:
smbldap-groupadd -a "People In Our Office"
Then get the output from
net groupmap list again and correlate the newly created group # just like last time, adding the group to the unix system:
groupadd -g 1001 samba_people_in_our_office
Add users to LDAP groups via the web interface, then correlate in unix:
usermod -a -G UNIX_GROUP_NAME UNIX_USERNAME
Also add computer accounts to unix, using the group "samba_domain_computers" from above, and where your allowed computer names end with a "$":
useradd -M -g 515 -s /bin/false officecomp1$
Last, but certainly not neccessary, you may want to turn off the unneccesary services CentOS runs by default. I determined that
I, specifically, don't need any of the following. You might be different, so look them up before you turn them off:
chkconfig ntpd off
chkconfig bluetooth off
chkconfig xinetd off
chkconfig smartd off
chkconfig yum-updatesd off
chkconfig rpcidmapd off
chkconfig rpcgssd off
chkconfig restorecond off
chkconfig portmap off
chkconfig pcscd off
chkconfig nfslock off
chkconfig mcstrans off
chkconfig mdmonitor off
chkconfig irqbalance off
chkconfig kudzu off
chkconfig ip6tables off
chkconfig hidd off
chkconfig gpm off
chkconfig haldaemon off
chkconfig autofs off
chkconfig avahi-daemon off
service ntpd stop
service bluetooth stop
service xinetd stop
service smartd stop
service yum-updatesd stop
service rpcidmapd stop
service rpcgssd stop
