With the LDAP KDB module, the expression is applied at the KDB layer via
an LDAP filter expression, as well as at the libkadm5 layer. LDAP
filter expressions can only handle '*' globbing. Possibly the LDAP KDB
module should check if  or ? is in the glob pattern and return all
results (like the other KDB modules do for all match expressions).

You might try "kdb5_util tabdump -n princ_tktpolicy" if you can run on a
KDC, or variations of that.
