In this example, I bind a Solaris 8 NIS client to a Solaris 10 DSEE 6.2 LDAP server and convert the following NIS maps to LDAP databases:

  • passwd
  • group
  • auto_master
  • Two non-standard NIS automount maps--auto_pra and auto_soft

Contents

Save the NIS maps as text files

Save the NIS maps as text files before binding the client to the LDAP server. As soon as you use ldapclient and bind to an LDAP server, /etc/nsswitch.ldap is copied over /etc/nsswitch.conf and your NIS client is stopped.

On the Solaris 8 NIS client: 

$ ypcat passwd > /tmp/nis_passwd_map
$ ypcat group > /tmp/nis_group_map
$ ypcat -k auto_master > /tmp/nis_auto_master_map
$ ypcat -k auto_pra > /tmp/nis_auto_pra_map
$ ypcat -k auto_soft > /tmp/nis_auto_soft_map

Bind the Solaris 8 NIS client to the LDAP domain

Example: 

# ldapclient -P simple -d subdomain.example.com -D cn=proxyagent,ou=profile,dc=subdomain,dc=example,dc=com LDAP_server_IP
System successfully configured

Create the LDAP databases

Perform these steps on the LDAP client.

passwd 

# ldapaddent -a simple -p -D "cn=Directory Manager" -h LDAP_server_IP -f /tmp/nis_passwd_map passwd
Enter password:
382 entries added

group 

# ldapaddent -a simple -D "cn=Directory Manager" -h LDAP_server_IP -f /tmp/nis_group_map group
Enter password:
29 entries added

auto_master

auto_master NIS map: 

/vol.soft auto_soft             -rw,intr,soft,timeo=7,retrans=9,noquota,vers=2,proto=udp
/vol.pra auto_pra               -rw,intr,soft,timeo=7,retrans=9,noquota,vers=2,proto=udp

Corresponding auto_master LDAP map (e.g., /tmp/auto_master.ldif): 

dn: automountkey=/vol.pra,automountMapName=auto_master,dc=subdomain,dc=example,dc=com
automountInformation: auto_pra -rw,intr,soft,timeo=7,retrans=9,noquota,vers=2,proto=udp
objectClass: top
objectClass: automount
automountKey: /vol.pra
 
dn: automountkey=/vol.soft,automountMapName=auto_master,dc=subdomain,dc=example,dc=com
automountInformation: auto_soft -rw,intr,soft,timeo=7,retrans=9,noquota,vers=2,proto=udp
objectClass: top
objectClass: automount
automountKey: /vol.soft

# ldapmodify -a -D "cn=Directory Manager" -h LDAP_server_IP -f /tmp/auto_master.ldif

automount

Because

auto_pra

auto_soft

auto_soft NIS map: 

sybase nvpmmnf604:/vol/pra_mh_citrix/mh-cx-pra/soft/sybase
remedy nvpmmnf604:/vol/pra_mh_citrix/mh-cx-pra/soft/remedy32
local nvpmmnf604:/vol/pra_mh_citrix/mh-cx-pra/local
soft nvpmmnf604:/vol/pra_mh_citrix/mh-cx-pra/soft

Corresponding auto_soft LDAP map (e.g., /tmp/auto_soft.ldif): 

dn: automountkey=remedy, automountmapname=auto_soft,dc=prammcx,dc=unix,dc=navitaire,dc=com
automountKey: remedy
objectClass: top
objectClass: automount
automountInformation: nvpmmnf604:/vol/pra_mh_citrix/mh-cx-pra/soft/remedy32

dn: automountkey=local, automountmapname=auto_soft,dc=prammcx,dc=unix,dc=navitaire,dc=com
automountKey: local
objectClass: top
objectClass: automount
automountInformation: nvpmmnf604:/vol/pra_mh_citrix/mh-cx-pra/local

dn: automountkey=soft, automountmapname=auto_soft,dc=prammcx,dc=unix,dc=navitaire,dc=com
automountKey: soft
objectClass: top
objectClass: automount
automountInformation: nvpmmnf604:/vol/pra_mh_citrix/mh-cx-pra/soft

dn: automountkey=sybase, automountmapname=auto_soft,dc=prammcx,dc=unix,dc=navitaire,dc=com
automountKey: sybase
objectClass: top
objectClass: automount
automountInformation: nvpmmnf604:/vol/pra_mh_citrix/mh-cx-pra/soft/sybase
