Adding a new attribute to the schema over LDAP

Steps

In a text editor, create an LDIF file with the new attribute definition.

Example:

In this example, the LDIF file is named myschema.ldif.

dn: cn=schema
changetype: modify
add: attributeTypes
attributeTypes: ( contractorStatus-OID NAME 'contractorStatus'
  EQUALITY booleanMatch
  SYNTAX 1.3.6.1.4.1.1466.115.121.1.7
  SINGLE-VALUE
  USAGE userApplications
  X-ALLOWED-VALUES ( ’Y’ ’N’ ’y’ ’n’ )
  X-ORIGIN 'PingDirectory Server Example' )

To add the attribute, run ldapmodify.

Example:
```
$ bin/ldapmodify --filename myschema.ldif
```

To verify the addition, display the attribute using ldapsearch.

$ bin/ldapsearch --baseDN cn=schema --searchScope base \
  --dontwrap "(objectclass=*)" attributeTypes | grep 'contractorStatus'

To view the custom schema file, go to <server-root>/config/schema/99-user.ldif.

Result:

For this example, you see the following details:

dn: cn=schema
objectClass: top
objectClass: ldapSubentry
objectClass: subschema
cn: schema
attributeTypes: ( contractorStatus-OID
  NAME 'contractorStatus'
  EQUALITY booleanMatch
  SYNTAX 1.3.6.1.4.1.1466.115.121.1.7
  SINGLE-VALUE
  USAGE userApplications
  X-ORIGIN 'PingDirectory Server Example' )
