NIS to LDAP example
From Brandonhutchinson.com
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 automount maps: auto_pra and auto_soft

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 to bind to an LDAP server, /etc/nsswitch.ldap is copied over /etc/nsswitch.conf and your NIS client is stopped.
On the 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 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 database (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
Before we can populate the non-standard auto_pra and auto_soft automounter maps, we have to add them to the automount map.
/tmp/automount.ldif:
dn: automountMapName=auto_soft,dc=subdomain,dc=example,dc=com automountMapName: auto_soft objectClass: top objectClass: automountMap dn: automountMapName=auto_pra,dc=subdomain,dc=example,dc=com automountMapName: auto_pra objectClass: top objectClass: automountMap
auto_pra
auto_pra NIS map:
mh-cx-pra-areas nvpmmnf604:/vol/pra_mh_citrix/mh-cx-pra-areas pra nvpmmnf604:/vol/pra_mh_citrix/mh-cx-pra/pra
Corresponding auto_pra LDAP database (e.g., /tmp/auto_pra.ldif):
dn: automountkey=pra, automountmapname=auto_pra,dc=subdomain,dc=example,dc=com automountKey: pra objectClass: top objectClass: automount automountInformation: nvpmmnf604:/vol/pra_mh_citrix/mh-cx-pra/pra dn: automountkey=mh-cx-pra-areas, automountmapname=auto_pra,dc=subdomain,dc=example,dc=com automountKey: mh-cx-pra-areas objectClass: top objectClass: automount automountInformation: nvpmmnf604:/vol/pra_mh_citrix/mh-cx-pra-areas
# ldapmodify -a -D "cn=Directory Manager" -h LDAP_server_IP -f /tmp/auto_pra.ldif
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 database (e.g., /tmp/auto_soft.ldif):
dn: automountkey=remedy, automountmapname=auto_soft,dc=subdomain,dc=example,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=subdomain,dc=example,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=subdomain,dc=example,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=subdomain,dc=example,dc=com automountKey: sybase objectClass: top objectClass: automount automountInformation: nvpmmnf604:/vol/pra_mh_citrix/mh-cx-pra/soft/sybase
