hi,
I have created custom object class and its attribute

attributetype ( 1.2006.08.20.1 NAME 'DealerCode'
DESC 'RFC2256: Dealer code'
SUP name )

attributetype ( 1.2006.08.20.2 NAME 'GroupCode'
DESC 'RFC2256: Group code'
SUP name )

objectclass ( 1.2006.08.20.3 NAME 'DealerMaster'
DESC 'Information regarding dealer'
SUP top STRUCTURAL
MUST ( DealerCode )
MAY ( GroupCode $ mail ))

i have stored this file in /etc/openldap/schema/dealer.schema then i have include this file in slapd.conf file then i have started server.
For testing purpose i have created one ldif file

dn: DealerCode=PankajB,dc=abacus,dc=com
DealerCode: PankajB
objectClass: DealerMaster

When i execute this ldif file with below mention command

ldapadd -x -D "cn=Manager,dc=abacus,dc=com" -W -f dealerentry.ldif

It ask for ldap password after entering the password

"adding new entry "DealerCode=PankajB,dc=abacus,dc=com"
appears on sceen then it hangs

Awaiting for your reply.
Thanks in advance

Check your logs, or start the server in debug mode to see if you find any hints.
Use another ldap utility, such as ldapsearch to see if it also hangs, that would mean a server problem, or a database problem.
Btw there is a nice tutorial here about adding custom schemas in openldap.

Regards

i have run ldapsearch command, it works fine also i have started server in debug mode it blocks at command
bdb_dn2entry("DealerCode=PankajB,dc=abacus,dc=com")
=>bdb_dn2id("DealerCode=PankajB,dc=abacus,dc=com")

after that it hangs

What version of openldap and BerkeleyDB are you using? I've seen the "hang" problem with openldap 2.4.16 and db.4.7 and the only way to make it work was using db.4.6!!!
Could you do the following test: After hanging of the ldapadd command, stop it using ^C and run ldapsearch and see if it finishes.
Also use "slapd -d255" for more verbose output.
