After a couple of months, I finally figured out how to create and maintain LDAP entries, connect them to GAL, and map attributes.
The problem I'm having now is that the mobilePhone mapping that I'm creating is NOT showing up on GAL item contact screen.
I followed the instructions to create this zimbra map entry:
mcf +zimbraGalLdapAttrMap mobile=mobilePhone
And I verified it was there by using this command:
/opt/zimbra/bin/zmprov gacf|grep zimbraGalLdapAttr
However, my GAL contact screen shows no mobilePhone field item even though I verified that the LDAP record has a "mobile" attribute with a value.
What else do I need to look at?
