adding custom attributes to openldap - openldap

Question

This is my first time at LDAP . I have setup an openldap on ubuntu machine and an ldap browser (phpldapadmin) on the remote system .I 'm trying to add two custom attributes to the cn=config and i get a successful message but if i see the attributes or the schema in the ldap browser its no where visible , please let me know where i'm going wrong . Below are the steps i have taken
1)Creating custom.schema file
#file to add custom schemas to the ldap
attributetype ( 1.7.11.1.1
NAME 'studentid'
DESC 'unique id given to each student of the college'
EQUALITY caseIgnoreMatch
SUBSTR caseIgnoreSubstringsMatch
SYNTAX 1.3.6.1.4.1.1466.115.121.1.15
SINGLE-VALUE )
attributetype ( 1.7.11.1.2
NAME 'pexpiry'
DESC 'indicated the date of password expiry'
EQUALITY caseIgnoreMatch
SUBSTR caseIgnoreSubstringsMatch
SYNTAX 1.3.6.1.4.1.1466.115.121.1.15
SINGLE-VALUE )
objectClass ( 1.7.11.1.1.100
NAME 'Studentinfo'
DESC 'Studentinfo object classes '
SUP top
AUXILIARY
MUST ( studentid $ pexpiry $
)
)
2)Create an ldif file
#ldif file containing the custom schema
dn: cn=custom,cn=schema,cn=config
objectClass: olcSchemaConfig
cn: custom
olcAttributeTypes: ( 1.7.11.1.1
NAME 'studentid'
DESC 'unique id given to each student of the college'
EQUALITY caseIgnoreMatch
SUBSTR caseIgnoreSubstringsMatch
SYNTAX 1.3.6.1.4.1.1466.115.121.1.15
SINGLE-VALUE )
olcAttributeTypes: ( 1.7.11.1.2
NAME 'pexpiry'
DESC 'indicated the date of password expiry'
EQUALITY caseIgnoreMatch
SUBSTR caseIgnoreSubstringsMatch
SYNTAX 1.3.6.1.4.1.1466.115.121.1.15
SINGLE-VALUE )
olcObjectClasses: ( 1.7.11.1.1.100
NAME 'Studentinfo'
DESC 'Studentinfo object class '
SUP top
AUXILIARY
MUST ( studentid $ pexpiry $
)
)
3)Add the ldif file to the cn=config using the below command
ldapadd -x -h 192.168.2.3 -D "cn=admin,cn=config" -W -f ./custom.ldif
It first asks for password , i enter the password and i get the message as
Adding entry "cn=custom,cn=schema,cn=config"
But when i goto browser i don't see the schema nor the attributes there .I tried to add an user it said invalid attributes .

Answer 1

1] Add custom schema in slapd.conf and restart LDAP service.If Everything is ok service will start properly otherwise it will give error.
2] After this if possible use Apache Studio for browsing,i was also not able to see the custom object in other browsers.
