In OPDK 15.01 you can recover a lost system admin password by following these steps. Note: you will have to know your LDAP system password in order to reset your system admin password.
Step 1: Run the following command to update the system admin password in OpenLDAP:
ldappasswd -h localhost -p 10389 -D "cn=manager,dc=apigee,dc=com" -W -s <new_password> "uid=admin,ou=users,ou=global,dc=apigee,dc=com"
Step 2: (OPDK 15.01 or newer) Run chpasswd-system.sh with the new password you entered in step 1 as the existing and new password. The chpasswd-system.sh script is located in /<apigee-install>/apigee4/bin directory. This script would update the apigee.conf file for the UI to the new password you have setup in OpenLDAP.
For OPDK 14.07 or older: use the EncryptUtil steps per this article to update the apigee.conf, not the chpasswd-system.sh script :
http://community.apigee.com/articles/1916/opdk-how-to-manually-update-ui-credentials-for-acc.html
If you have multiple MS servers, you will need to run chpasswd-system.sh on each MS for OPDK 4.15.01 or newer, to update the apigee.conf on each MS server. For 14.07 or older you would have to use the EncryptUtil on each server
Please share the instructions to reset lost sysadmin passwd for the latest version since there is no chpasswd-system.sh in the new version.
No problem I tried below steps and it worked.. ! Hope you can include this in the operations guide
1. stop edge-ui
2. ldappasswd -h localhost -p 10389-D "cn=manager,dc=apigee,dc=com"-W -s "uid=admin,ou=users,ou=global,dc=apigee,dc=com"
3. Update the configfile with the new admin password.
4. /opt/apigee/apigee-setup/bin/setup.sh -p ui -f configFile
