Release 7.1.2_GA_3268.UBUNTU10_64 UBUNTU10_64 NETWORK edition.

We are using external AD as GAL.

On one specific user, we now have two records in GAL, but only one in AD.
In GAL, one record is with new mail-address and one with old mail-address.
This happened after changing mail-address in AD.
Has searched via LDAP and find only one record in AD.

Has tried "zmgsautil fullSync" and "zmgsautil forceSync".

Anyone know how to totally clear the cached GAL-data in Zimbra, so that I can set up and sync it from AD all over again?
