How to unlock orcladmin
You should use the "oidpasswd" utility to unlock the orcladmin account. Do not confuse this account with the default realm administrator "cn=orcladmin,cn=users,dc=xxxxx,dc=yyyyy".

1. Unlock the orcladmin
$ oidpasswd connect=your-database-sid unlock_su_acct=true
OID DB user password:
OID super user account unlocked successfully.
This unlocks the OID Super User account, cn=orcladmin ONLY. They are two separate accounts. After resetting the orcladmin super user account, you will still not be able to login to SSO using the orcladmin account until you perform the next step.

2. Launch the Oracle Directory Manager:
On unix: run the oidadmin command
On Windows: Start/Programs/Oracle AS10g/Integrated Management Tools/Oracle Directory Manager
Note: the ODM tool must be a 10g client.
Using the left menu tree, navigate to Password Policy Management. You will see TWO entries:
cn=PwdPolicyEntry
Password Policy for Realm 

3. Edit each of these and change the Password Expiry Time (pwdmaxage) to an appropriate value
5184000 = 60 days (default)
7776000 = 90 days
10368000 = 120 days
15552000 = 180 days
31536000 = 1 year
999999999 = never expire 

4. Launch the Oracle Directory Manager and navigate to the realm specific orcladmin account... Entry Management > your_realm > cn=Users where all the users a
re located. Click on the + next to cn=Users. The list is in alphabetical order. 
Locate the cn=orcladmin entry. Find the userpassword attribute and reset the value. 

5. Try the ldapbind again.
$ /u01 $ldapbind -p 13061 -D cn=orcladmin,cn=Users,dc=organization,dc=gov -w xxxxxxx7orcl
bind successful
$ /u01 $ldapbind -p 13061 -D cn=orcladmin -w xxxxxxx7ias
bind successful

6. Know after testing all binding is successful you can add an entry to OID.
