LDAP password change after migration

Installed zimbra 7.1.4 from scratch and migrated all the data from 7.1.2 to new server from old server.
No problems except LDAP.

Zimbra New version
Release 7.1.4_GA_2555.SLES11_64_20120105094644 SLES11_64 FOSS edition.

Zimbra Old Version
Release 7.1.2_GA_3268.SLES11_64_20110804130756 SLES11_64 FOSS edition.

The Problem:
All users have old LDAP password to query zimbra GAL from outlook 2007 clients address books.After migration they are unable to query users mail addresses in outlook address book because the LDAP password has been changed.

Tried to find some guides about changing password found two:
Setting zimbra admin password in LDAP
Setting zimbra admin password in LDAP - Zimbra :: Wiki

Resetting LDAP and MySQL Passwords
Resetting LDAP and MySQL Passwords - Zimbra :: Wiki

No information about 7.1.4 at all. Also there are several differences between configurations 7.1.2 and 7.1.4 in /opt/zimbra/conf/localconfig.xml.

Old Server:
ldap_amavis_password = lm*****o
ldap_nginx_password = lm*****o
ldap_postfix_password = lm*****o
ldap_replication_password = lm*****o
ldap_root_password = lm*****o
zimbra_ldap_password = lm*****o

New Server:
ldap_amavis_password = UQ******LN
ldap_nginx_password = UQ******LN
ldap_postfix_password = UQ******LN
ldap_replication_password = UQ******LN
ldap_root_password = UQ******LN
zimbra_ldap_password = UQ******LN
ldap_bes_searcher_password = UQ******LN (NEW VARIABLE)

After changing all LDAP password using "zmldappasswd -a -l -n -p -r" (as described in IT Support Blog » Zimbra) all passwords looks OK. Same as the old server. Users can query mail addresses and everything.

BUT
as soon as the kerberos ticket expires (I think because it takes about 5 minutes for users to rain phones on IT dept.) after that NEITHER we can login to zimbra administrative page NOR users can send mail (strange thing is that they can receive mails !!!).

Administrative page says as
