quick notes

http://znogger.blogspot.com/2010/05/solaris-automatic-creation-of-home-dirs.html

add a line to /etc/auto_master

echo "/export/home/ad /etc/auto_homedir" >> /etc/auto_master

create the /etc/auto_homedir script

root@ueq2szsapapt01:~# cat /etc/auto_homedir #!/bin/bash

( HOMEDIRPATH=/export/home/ad PHYSICALDIRPATH=/export/home/.ad HOMEDIRGROUP="" hdir=~$1 E=getent passwd $1 |wc -l if [ $E -e 0 ]; then exit fi sanitized=echo $1 | sed 's/\//_/g' phdir="$PHYSICALDIRPATH/${sanitized}" if [ -d "$phdir" ]; then echo "localhost:$phdir" exit fi mkdir -p $phdir chown "$1":"$HOMEDIRGROUP" $phdir echo "localhost:$phdir" exit ) | tee /tmp/autohome.log

Set sticky bit and execute on the script

chmod +t+x /etc/auto_homedir

Restart the automounter

svcadm restart autofs

Create the base mountpoints

mkdir -p /export/home/ad

mkdir -p /export/home/.ad

Solaris Samba Server Configuration Steps

– Configure DNS Client
Configuration must include Windows AD Servers as DNS Servers and specify the AD Domain as the DNS Domain

/etc/resolv.conf

nameserver 10.x.x.x
search example.com

– Configure Kerberos
Create /etc/krb5.conf

[libdefaults]     default_realm = EXAMPLE.COM     dns_lookup_realm = false     dns_lookup_kdc = true

– Confirm system time is synchronized with AD Servers. NTP is recommended to keep system time accurate.
Difference of 3-5 minutes between the Samba and AD Servers will result in Domain join failures

# ntpdate ad.example.com

– Samba Server local hostname / nodename resolution must be a fully qualified hostname.
The /etc/hosts entry for the Samba Server needs to be a FQDN to avoid Domain join failures

/etc/hosts

10.x.x.x      host.example.com    host

# getent hosts host
10.x.x.x      host.example.com    host

If modified after initial configuration boot up it can be modified with the command:

# svccfg -s svc:/system/identity:node setprop config/nodename = host.example.com
# svcadm refresh svc:/system/identity:node

– Create the /etc/samba/smb.conf file.

[global]

       realm = EXAMPLE.COM
       workgroup = EXAMPLE
       security = ADS
       server string =Solaris Samba Server
       kerberos method = system keytab
       include system krb5 conf = no
       loglevel = 10

      # Winbind configuration:

       winbind separator = /
      # set enum=no , this increases performance considerably
       winbind enum users = no
       winbind enum groups = no
       winbind expand groups = no

       template homedir = /export/home/ad/%D_%U
       template shell = /bin/bash

       idmap config * : backend = autorid
       idmap config * : range = 100000-4000000000
       idmap config * : rangesize = 1000000

       allow trusted domains = yes
       winbind refresh tickets = yes

     # all these are addons
#winbind use default domain = Yes
local master = No
preferred master = No
bind interfaces only = Yes
name resolve order = bcast lmhosts host wins
dns proxy = no
unix extensions = no
domain master = no
socket options = TCP_NODELAY SO_KEEPALIVE
client schannel = no

– Edit the /etc/nsswitch.conf to add winbind to the passwd: and group: entries if AD username and group resolution for files and directories is needed

Solaris 10

passwd: files winbind [ TRYAGAIN = 3 ]
group: files winbind [ TRYAGAIN = 3 ]

Solaris 11

# svccfg -s svc:/system/name-service/switch setprop config/default = astring: files
# svccfg -s svc:/system/name-service/switch setprop config/password = astring: “files winbind [ TRYAGAIN = 3 ]”
# svccfg -s svc:/system/name-service/switch setprop config/group = astring: “files winbind [ TRYAGAIN = 3 ]”
# svccfg -s svc:/system/name-service/switch setprop config/host = astring: “files dns mdns winbind”
# svccfg -s svc:/system/name-service/switch setprop config/printer = astring: “user files”
# svcadm refresh svc:/system/name-service/switch

The next steps are to enable the samba and winbind services and join the Samba Server to the Windows Domain,
To join the Domain a system administrator will use a Windows Domain username that had administrator rights, privileges in the Windows AD Domain.

– Enable the Samba service

# svcadm enable samba

Confirm the samba service is online

# svcs samba
STATE          STIME    FMRI
online         15:06:22 svc:/network/samba:default

– Join the Samba server to the Domain as a User with Windows Domain Administrator rights

# net ads join -U <USER>
Enter <USER> password:
Using short domain name — <DOMAIN_NAME>
Joined ‘<HOST>’ to realm ‘<DOMAIN_NAME>’

Enable the Winbind service

# svcadm enable winbind

– Wait 2-3 minutes for winbind Service to initialize

– Confirm that the samba and winbind services are online:

# svcs samba winbind
STATE          STIME    FMRI
online         15:06:22 svc:/network/samba:default
online         15:09:55 svc:/network/winbind:default

– Confirm that winbindd can be communicated with and return ADS usernames and groups with the commands:

wbinfo -p
wbinfo -u
wbinfo -g

– Confirm that the Solaris NSS functions (configured via the /etc/nsswitch.conf) can return Windows ADS user information

getent passwd | grep Windows_Domain_Username

For example:
# getent passwd | grep <USER>
<DOMAIN_NAME>+<USER>:*:<UID>:<GID>:<USER>:/<PATH>/<USER>:/bin/csh

Once completed a Windows Client system should be able to map a share from the Solaris Samba server and authenticate using the users Windows Domain/ADS username and password.

– If it is intended for ADS users to login to the Solaris Samba server via ssh or telnet a pam.conf file with winbind references should be moved into place.Note: Solaris 10 with Samba Patch 119757-20 SPARC / 119758-20 X86 or later installed the pam.conf-winbind2 file provided as a attachment in Document 1413786.1 should be used in the following steps

# cd /etc

# cp pam.conf pam.conf.bak

# cp pam.conf-winbind pam.confNote: In Solaris 11.1 and later the PAM configuration has been updated. To add the Winbind PAM module to the configuration make the following modifications

Edit the files located under /etc/pam.d/ and add the line for pam_winbind.so.1 as shown in each one of the following files.
